Hand 1) I would make it bigger pre-for sure. Maybe your sizing IP, but OOP $7-$8 probably.

As played, I'd imagine if fish is so bad, cold call can be much wider than normal. I'd cbet here, it looks mega strong.

Hand 2) Guy is pretty tight, I don't hate a fold pre. If I call pre it's cause I think he's loose enough to call pre, and I'd peel this flop.

Hand 3) I don't think the Q is a big enough scare card to get many folds out of his flop calling range. People show up with AQ here as well. I'd shut down.
