Hand 1: seems fine to me. If I knew the UTG raiser (and/or MP) was tight, I might dump this on the flop after his reraise and the coldcall.

hand 2: fold the turn. Mostly I would just call the flop and bet turn if checked to.

hand 3: Fold flop. Please fold it. Dont play for stacks on the flop with an overpair without reads and you NEVER do it 200BB deep.

hand 4: Raise to 1 prf. A good general rule of thump is to raise 3.5xBB+1 pr. limper (make it 4xBB+1prlimper when playing as low as NL25). Bet more on the flop, lead turn and look to get it allin somewhere in between without betting so big that you chase opp out. I checkcall river to lose the least against a full house and to give busted draws an opportunity to take a stab at the pot.

Hand 5: Bet the flop (unless you've been caught cbetting a lot lately). Call on turn is fine. The river is tricky and depends on your opponent. Against certain opps I just call river, against fish that I know play weak aces I make a valueraise like you did (make it at least 10 to go though)
