Since they've probably lost at least some roots to rot, the score's not in yet on those guys. I'd be giving them some TLC in the form of a week in a shady spot to rest up and see if they can recover, grow more roots and resume their normal growth.
When you start seeing lots of nice healthy new leaves,that's when you know things are looking up. There's new growth on all of them, but it's too soon to tell if it will get to normal size.
Ease them back out into the sun again, just like your nursery transplants. Sudden change is never easy on a stressed plant. Patience is the foremost lesson you learn as a gardener. It's a great life skill to have but SO hard to acquire!
You're asking good questions and doing a great job.
