Give them another soak if you haven't already. That looks as if there was severe heat to do all that damage. Keep them 'cooler' and damper with fairly low light levels to allow them time and ability to recuperate.
You can bring them inside right away if you want. There should not be any negative repercussions. To be honest, the damage on your plants does not look that bad and they all should recover very well. I'm in Austin and most of my plants are outside without any problem, though I did have to bring in my Dend. Aussie Chip which has started looking rough after 55 days of 100 plus temps and 80 degree nights. Don't forget that a lot of your plant's energy comes from sunlight. Keeping them in deep shade for a long time will most likely hinder their recovery. The fact that your plants all survived such an ordeal shows how healthy they were before their mistreatment and is a tip of the hat to their care taker. Keep up the good work!
I would wait a bit. It might take a few weeks to see the full extent of the damage and while your plants look good for what they went through, they are still stressed and any further stress might be counter productive. Keep an eye for any mushy spots on the dead parts and cut those off ASAP. Otherwise, I would personally let them recover for the time being.
Your plants are severely dehydrated and sunburned. Watering will take care of the deyhydration. As for the sunburned leaves, while they're unsightly, they still continue to support the plant. Leave them be and very gradually they will be replaced by new leaves. You might consider using some triple antiobiotic cream from the drug store on the damaged leaves to prevent infection.
As the other said, it is a pitty, but the damage does not look so bad... all plants should recover easily.. follow the directions given already..
if it helps, I had worst results in my Greenhouse (being attendted by me!) in one day that the weather suddenly changed from "spring cloudy and cool" to "way too early super sunny and super hot pre-summer" and I had not put the shadecloth yet... about 30% of my plants heavily burned, several bloom spikes and buds aborted and 3 Catasetinae completely gone...
just be angry with the caregiver and let them kno wthat (but ONLY if you really gave instruction how to care for the plants and explained they should not be outside by any meanings! - most people are not aware of this)
