Hand 1: Only been at the table 5 minutes. Villain seems very aggro to me. Last hand I raised him blind-on-blind with KTs, flopped middle pair on AT6 board and he min-raised me and I just folded. Very next hand:

SB bets $40, Hero ???

Hand 2:Villain is semi-loose and donkish. I believe he's on a draw or some middle pair type hand. I raise the flop because I've seen the initial donkbetter do this with draws and bottom pair hands. On the turn I try to rep the Ace but it doesn't work out. What to do on the river to maximize EV? Check and most likely lose the pot or shove and try to get him to fold?

#1 Hero calls all-in. It's not the greatest situation but you obviously have outs against anything he can have, and if you think he's aggro his range is very wide here. He may even have a lower FD and be drawing almost or completely dead.

#2 Hero checks behind ... he will show up with Ax very often, and if not he has a flush draw and you are ahead most of the time anyway. I think he has a hand that beats you that will fold to a bet like 10% to 20% of the time max.
