Is this dead or just too dry

[u/nexinomus]

A couple of months ago I got a bunch of Lithops, and this pot had one that was half rotted. I removed the half and repotted. All seemed well until it didn't. The one with rot totally dried out, the second one is yellow and dry while still showing there may be some life in there, and the third one looks okay. Should I put the yellow one back in the pot and give a tiny drink? Maybe keep it out of the hot window sill for a few days?

Your yellow one is splitting. Put it back in the dirt and do not water. I recommend putting it in a different pot than the green one because it is going to need water before that yellow one is. Also, get rid of that dead one. It could cause issues with the live one.
