The LR will be fine..
Is the temperature down below 83 in your friend's tank? I'd worry about the shock of acclimating already stressed corals to a new tank. Multiple good sized water changes over the next couple of days should help lower toxins.
If there are some really prized corals, and they're heading downhill, you might try a water change first, and then try moving to your tank as a last resort. Just don't move so many to your tank that you risk your own water quality if they don't make it.
