Basically, the entire forest itself was an illusion and so were those guys just some illusions that are given form by Goku and Krillin's Ki which is why Tambourine had just as much power as Buu. The illusions become tangible because of the Ki that aliments them, so no NPI. As for resistance, those illusions are dependent on Ki and memories. It's not like they actually resisted being placed under illusions, but they simply exploited the illusions' weaknesses and thus countered them by calming their minds and no longer emanating Ki to feed the illusions. And that was exactly their test
