Will they survive?

Ordered some perennial plug plants from T&M. For some reason the delivery took a week with them stuck at royal mail over the weekend. It’s been super hot and dry so they’ve taken a bit of a battering. That said, when they arrived they looked better than I thought they would. Some are clearly gone but most appear to have some life left.

I’ve potted them all up and given them a drink. Will wait and see, but what do people think about the chances they will survive? Are there any clear signs that they are past it?
