They all look healthy and plump, so I see no reason why they will not re-root. I would pot them up in your usual potting mix and put them in a shaded position. Keep them damp but not wet and if you can give them a bit of bottom heat, it should encourage the roots to come out quicker.
Good luck with them and please keep us posted on how they go on.
