When you're playing with people this passive and loose, they won't fold, but they will give you free cards.

I'd check the turn in all hands and see if they'll give you a free card (or just to take one). It happens quite a bit. If they bet at you, they probably have something, and you can fold.

You've gotta check the river behind in hand 2. You're not going to be called by anything you beat.

Edit: You said they'll call a lot with high card, but are they bad enough to call with J high or worse? I don't think you'll win often enough when called, even if there is a chance you'll win when called.
