is it dead

Likely so. You could try to keep it going but if it does not recover in a few hours it will be a loosing battle.

What happened? The other plant is not wilted.

I transplanted it 2 day before from a 4 in container it looked good but then it did that now there's two of them like that. Thos are my other ones all got transplanted from 4in to 3 gallon except 3 of them
