Although these plants look severely dehydrated, their roots seem healthy, so it should be possible to revive them. It looks like they are in a bark mixture right now (yes?); usually when I get a rescue, especially a really thirsty one, the first thing I do is repot it into soaked sphagnum moss so that it has the benefit of a nearly constant moisture supply. Keep it moist all the time until you start seeing signs of revival. Also moving the plant into a humid area such as a bathroom, or even putting a plastic bag over the top to hold in moisture can help quite a bit.
The leaves the plant has right now will never fully regain their turgidity and former height, but they will probably perk up somewhat after a couple of weeks with a decent water supply. New leaves will be normal and healthy, and will also be a sign that you're doing it right. Be patient and give lots of love
I wouldn't remove any leaves at the moment unless they are clearly yellowing and ready to fall off.
