That one side is pretty bad. That hit something, it's not just from jacking.
(pardon my liberties with your pictures)
This is the other side? Also not great. Maybe it went off road and landed on something straight across both sides.
I would want to do something about that. Perhaps have a steel bar or angle or even U-shaped piece welded on there. I'm going to guess $400 from a shop or $100 plus some beers if you know someone who welds. It doesn't have to be pretty. You may also want to have the alignment checked before and certainly after - good luck. I have not had to deal with damage like that, perhaps someone else will comment.
The rest looks fine, and it doesn't look like you have the rot / rust at the front of the frame where it curves up into the engine bay - that is good.
