well they may be gone for ther most part sadly.
Just let them be in a bright room with their rooting bottom away from any water for now. Spray the leaves to foilar feed the plants, just place you hand on the plant bopttom as you spray or place a plastic bag on the bottom as you spray them, and place them on a slotted tray on top small pebbles to keep them humidified with out being wet. Understand ? ,no direct water just a slightly humid enviroment to keep the leaves from shivering up on you. This willl be a get well nursery. Quite a trial to save them .I have do this myself and learned throuh trial and erroe. No watering just foliar feed unitl they decide to regrow thier roots on thier own and then use small chunks of orchid potting soil. do you have any "SPray and Grow" or Superthrive around foiliar ffed with this for a while. I hope it works Let me know
