Here are my thoughts w/ no reads on the players...

Hand1: pop him back preflop, make it 90$ to go. if reraised, you can lay it down knowing he has AA. If he calls, check raise him on the flop, if he comes over the top, fold cause you're beat w/ a set or AA.

Hand2: hard to get away from that one ;-) FWIW, I'd raise him on the flop, and try to get my money in.

Hand3: sorry, but I don't like it for two reasons...
1) the board paired on the flop, your flush or str8 could be dead.
2) its multiway, and you could be against a higher flush draw.
The flop call of $25 is ok, but I'm folding on the turn.

Hand4: touch situation. is he the type of player capable of moving on high cards?
