I would consider folding third, especially if the table is at all loose. There are a bunch of low cards yet to act, and it's not like the Ten in the door disguises your hand that much.

By fifth, I think the other guy has let you know that you're behind. Hopefully he has Aces, but he could well be rolled, or maybe he is a goof with two Jacks in the hole. None of this is good news. Anyway, I don't think he's putting in all that action with anything you can beat.

On sixth, he's hit an open pair. You're drawing to two outs against Aces-up, and you're drawing dead against a full house. You don't have odds to call. This is an easy fold unless the guy is a known loon.
