I'm new to $1kNL and have no stats on villain. This hand is standard right?

Villain is Ehsan666. Anyone know anything about him? He seems like a a very loose losing player.

I feel I played this hand so, so badly. I should definitely fold to the final allin bet preflop. I just don't have a chance of winning. The odds were quite good though, so I just didn't want to fold.
This is one of the few hands I played really bad today.

Are these hands alright? I hate the 3rd one, but what about the 1st two?

I've been playing very well. Winning $9.4k in 2days, but I just dropped $2.6k so I want to make sure I'm playing OK.
I did lose a $2.4k pot with AA vs JJ allin pf, so I'm not too worried.
