Hand 1 is standard and there's nothing else you can do on the flop, I probably try to get it in preflop though.

Hand 2 is also standard but I don't know why you need to bet so much on the flop

Hand 3, why overbet so much on the turn? Just bet ~$2.00 and get it in on the river. Without reads this isn't really an interesting hand.

Hand 4, fold preflop. Flop is good imo but a weird spot that I don't get myself into much so I'm not sure. Turn, you should either be betting more or checking through imo. River is good.
