I don't think they are goners.
I've had plants look like that and all they needed was water.
Did you try hand watering them?
I think they are far from being dead or even that injured.
Looks like a couple must have roots in the water and didn't get hassled much at all.
POP the top and treat them like an ebb and flow with you being the water pump a couple times a day until you get a new pump.
