i called here hoping someone behind me would squeeze light since there were 3 people behind me with 11% + 3bet

how do I figure out what's best on this flop once opener checks to me? there's quite a lot of turn cards I won't like and it's 4ways and i'm oop so I decided to bet to protect.

on this turn would you bet/call ??

i'm new to 2/4 and am NOT at all used to overbets... what can I do on this river? i can't see gotigers checking TT or 9T on this flop... so what Tx can he have?
