hand 1 looks fine

hand 2 you dont give any reads but if he's particularly aggro chk raise all in would be good. if not then i would prefer bet fold to check fold.

hand 3 sometimes ill check the turn to induce a river bluff but your line is fine to.

hand 4 fold the flop. turn an river are very meh. messy hand.

hand 5 looks good. i presume you were folding to a push on the river?
