Wow, some one forgot to tell the nursery they are drought tolerant.
Good photos John.
First step, remove all damaged roots and leaves. All of them.
Leave them to dry for several days, out of direct sun.
Once thoroughly dry place into fast draining soil with a top dressing of chicken grit/pea gravel.
Water sparingly. Still keep them out of direct sun, but need bright light/filtered sun.
You may be able to save them all.
