Here is a list of all the gods who either scale from Neith and those who scale from her, and/or have feats or scaling apart from her. For a reference of how powerful Neith is for this scaling, she created the universe and existed before it when nothing but the black waters existed.
Ah Puch: Should scale from Camazotz as a fellow god of the Mayan underworld
Amaterasu: Should be roughly on par with Zeus as a fellow pantheon leader
Anhur: Should scale with Rather, Bastet, and Apep/Aphophis and fought a long battle against Ares
Anubis: Was evenly matched with Base form Hades and fought Camazotz, though was slain brutally by Ares
Ao Kuang: Fought both Zeus and Hel in the comics and in his lore he fought Ne Zha
Aphrodite: Should scale with the other Olympian gods
Apollo: Should scale with the other Olympian gods
Ares: Fought Athena to a stand still, killed Chaac (while he was off guard), killed Anhur, beat the shit out of Ra, and killed Anubis
Artemis: Should scale with the other Olympian gods
Athena: Fought Ares to a stand still, fought Loki (with Zeus' Thunderbolt) twice, but had to be saved by a standard frost giant by Nox.
Bacchus: Should scale with the other Olympian gods
Baron Samedi: Could block a blow from Bellona with his cane and considering Bellona came to him for aid he should be pretty powerful
Bastet: Fought alongside Ra and Anhur against Apep/Aphophis
Bellona: Should scale to the likes of Ares and Athena, and has fought Chernobog and Ragnarok Hades and survived her first encounter with Pele
Cabrakan?: This one is iffy due to scaling around Xbalanque BEFORE he became a god
Camazotz: Fought Anubis
Cerberus: Fought Hercules during his trials and is the guard dog for Hades
Chaac?: Also iffy as Ares killed him when he was off guard
Chang'e?: Sister of He Bo

Cupid: The son of both Ares and Aphrodite
Discordia: Should scale to her mother Nox and her two siblings Thanatos and Nemesis
Erlang Shen: Fought Sun Wukong
Fenrir: As a son of Loki and sibling to Hel he should scale to them, plus he is destined to defeat Odin at ragnarok
Freya: As one of the more powerful Norse gods she should scale with the likes of Thor or Odin
Ganesha: His power kept Ares from entering his temple and he should be on par with other Hndu gods
Geb: is the son of Ra and is the father of Isis and Osiris, and is the earth itself in Egyptian mythology.
Hades: Base and Ragnarok forms
He Bo?: Is just a river god but he kept Ares from crossing his river until Ares threatened the nearby mortals
Hel: Fought Zeus, Loki (with Thunderbolt), Ao Kuang, and Sun Wukong.
Hera: she IS coming to the game soon so I'm counting her, and as the queen of the greek/Roman gods she should be fairly powerful
Hercules: Has beaten Base Hades, Cerberus, and Thanatos, among a lot of other feats
Hou Yi?: husband of Chang'e and brother in law of He Bo
Hun Batz?: Like Cabrakan questionable scaling around Xbalanque
Isis: Poisoned Ra into giving her a lot of power over him
Izanami: Is one of Japan's most feared gods and is the mother of Amaterasu and Susano'o
Janus: Should scale with the likes of Nox, Discordia, Thanatos, Nemesis, and Terra as he to is a primordial god
Khepri: Should scale with Ra as a fellow Egyptian Sun god
Kumbhakarna: The brother of Ravana Loki with and without Zeus' Thunderbolt:
Mercury: Fought against Loki (with Thunderbolt) and is one of if not the fastest gods
Ne Zha: Fought Ao Kuang and Sun Wukong
Nemesis: Is feared by many Greek and Roman gods like Zeus and should scale with the likes of Nox and her siblings
Nike: Fought against the titans alongside Zeus and it's been said Zeus and the Olympians may very well have lost without her aid
Nox: The Olympians are weary of her power and she saved Athena's life from a frost giant
Odin: As a pantheon head he should scale to the to the likes of Zeus and is destined to do battle with Fenrir
Osiris: Is the son of Geband husband of Isis, but WAS butchered by set

Ra: Fought Apep/Aphophis daily and as a Pantheon head he should scale to the likes of Zeus, but had the tar beaten out of him by Ares
Raijin: Is the brother of Amaterasu and should likely scale to her
Skadi: If a standard frost giant could nearly kill Athena, Skadi, a frost giant turned goddess, should be relatively powerful in her own right and she was ready to fight the Norse gods solo until they befriended her
Sobek: Should scale with Neith as he is her son and has existed almost as long as her and aided with the creation of the universe
Sun Wukong: Fought the likes of Hel, Ne Zha, and Erlang Shen and his cudgle was capable of breaking the binds of Fenrir
Susano'o: Is the brother of Amaterasu and should likely scale to her, but he also outsmarted and killed Orochi, a beast even gods couldn't easily slay

Thoth: His book contains the knowledge and power of universe with a single flip of the page settings gods on edge, and as a moon god opposite of Ra he should scale with him as well. He has also aided Ra against Apep/Aphophis, taught Isis magic, and cleaned Horus of Set's poisons
Thor: Fought against Loki (with Thunderbolt) and is among the Norse pantheon's strongest fighters and is shown to be on par with Athena
Tyr: Is the Norse god of war and law, and is one of the pantheon's strongest champions despite having lost an arm to Fenrir Ullr: Is the only god Odin would trust the thrown to in his absence, which should speak volumes of Ullr
Vulcan: Is responsible for almost ALL the weapons, armor, and chariots used by the Greek/Roman gods, and could craft a booby trapped throne even Hera couldn't escape
Xbalanque?: This one is hard to judge. As a demigod he did trick the likes of Cabrakan into eaten poisoned meat, and hid from Camazotz but later bested the gods of the Mayan underworld with skill and athleticism in the ball game Pitz
Awilix?: Xbalanque is technically her reincarnation but given how wonky his scaling is...
Ymir: Is THE primordial frost giant who ALL Norse gods and frost giants came from, and fought Odin and his brothers

Vamana: Like Rama is an avatar of Vishnu and can grow to the size of a universe
Xing Tian?: In Chinese mythology he is destined to fight the highest gods of creation

Parvati: Wife of Shiva
Izanagi: Father of Amaterasu and many other Japanese gods and husband of Izanami.
Fujin: Brother of Raijin and Amaterasu. Constantly battles Raijin
Yamato No Orochi: Not even gods could easily slay this foe
This list is for people who don't really scale from anyone or who's feats don't put them in range with the others at all. This list includes both game and lore characters.
Game: Achilles: DOES have armor made by Vulcan and is supposedly impervious and the gods supposedly fear him...but this isn't much to go off of
Ah Muzen Cab
Arachne: the best she has is a web that she can flip up to that allows her to travel anywhere...oh and she beat Athena at...sewing...
Artio: Is a living constellation sure, but she doesn't have much besides that to work off of
Bakasura: Did fight Bhima but as Bhima isn't in the game it's hard to judge if Bakasura should scale yet or not
Chiron: Trained Hercules and Achilles but training does not exactly equal feats
Cu Chulainn: Fought the Morgan but sadly she lacks feats and so does Cu Chulainn
