Really good to see you on 5NL tables. Keep that disipline and you will soon be up to higher tables again.
Hand 1: I agree you can not fold, you might be beat but pot odds combined with passive opponenet suggests a call in order.
Hand 2: Also a call if you had any more money it would be a shove. Youre bet sizing was a bit small again especially on Turn and river I would have pushed all in on river but as it is you got all the money in. The raise on the end looks like a big stack trying to bully after you showed a bit of weakness on the river.
Hand 3 is a laugh but be careful you slow played those aces along time allowing so many free cards will hurt you eventually.
