hand 1, I bet less, like ~$2, and fold to raise, unless I am convinced that villain will shove with air here. Also, I fold PF AT, but maybe I'm a nit.

hand 2, I am more willing to call against any villain who is not playing 18/13 type game... Many villains here are raising draws or overcards since there was no paint on the board and they feel they need to double up.
Actually, in hand 2, I probably bet pot on the flop against a non nit and call a shove. But really this would be read dependant, many players at these stakes go nuts when they're very short
