Help me with these horribly played hands.

[jquattro]

Hand 1: I don't call the preflop raise with k8o, however looking at everyone else's responses, I assume I should be. Though I'd only think about it against high pfr players.
Hand 2: I always bet the turn here, and if called, I'd bet against loose passives, check/call LAGs and check/fold tight players.
Hand 3: I bet turn and fold to a raise, then check/fold if called.

Some answers may change depending on the players stats in each hand.
