I used to think situations like hand #1 could be considered a fold but I saw too many people stacking off with AT, AJ, KQ, AA, TT, 22 etc in these pots. And it sounds like the players aren't too good on your network so I would stack off here for sure.

In hand #2, I would still call the turn. Shitty players love to bluff paired boards for some reason. Unknown = shitty. If he fires the river again I fold I guess. And a mini-raise does not equal strength from a shitty player. A mini-raise = some guy that doesn't know what the fuck he's doing, whether it's a bluff or a value bet.
