Er, it looks like you do have something significant (but definitely repairable) going on in picture 2. Is that the step well or is that a rear wheel well?
Not bad at all, it's ok it's not GM rust either LOL
I call that surface rust at the worst. Maybe a little sorta worse on that wheel well but that's still no big deal at all. Fame and all looks perfect to me.
