Hand 1 - I would c-bet frequently, but not all the time. You only have 2 opponents and it's a very scary flop so impossible for one of them to continue unless they have a strong hand.

Hand 2 - fine.

Hand 3 - Fold turn/fold river. At these stakes and FR, the flop raise+turn bet has you beat all the time. It sucks to fold a set/FH but that Q is terrible for you.

Hand 4 - I'd probably check the turn here as well. No one will fold a little flush. You're charging a set to fill up which is fine, but the value of that is pretty slim.
