2/4 NL Stars, Covering the table, Flopped Set, Should I FOLD ???

I dont know the exact chip amounts but remember the hand as clear as day. 9 players (am gonna mention the relevent ones).

SB Hero ($888) Dealt 22

MP1 ($450ish)

CO Villain #1 ($350ish)

Button Villain #2 ($420ish)

MP1 raises to $16, Co calls Button calls and I call Preflop.

Flop

8 3 2 RAINBOW

Orignal Raiser MP1 bets $40

CO (Villain #1) raises to $90

Buttton (Villain #2) smooth calls

HERO ?????????????????????????????

How many are gonna muck the 222 here???? Keep in mind this is 2-4 not 5-10, I have seen a lotta BS here like Villain #1 pulling out 99 or maybe Button having 45, but I dont know these players , never seen them , and have no reads. Only know MP1, who was the preflop raiser, and is reasonably solid (I think he is mucking after this action anyways)
