I feel like they all could of survived if they had just stayed put....
I could be wrong here but they would of all survived if they had just stayed on the lift. Yeah they froze at night but as we saw the sun thawed them out during the day. It may not of been enough to keep some level of frost bite away, but just enough to keep them alive. They could of survived 5 days without food if they had just sucked on those ice cycles for water.
By the time the girl got down it was Wednesday? Maybe Thursday? She had a little frost bite in some places, but other than that she was fine. So they could of all made it one more day.
