I have read no one from Star Trek liked Shatner. Have no idea if it is true.
I dunno whether Nimoy liked Shatner, but they socialized as none of the others did while the show was active, and Nimoy tried to reconcile Shatner with some of the others long after the show was done. Everyone liked Nimoy; no one liked Shatner... except maybe Nimoy.
After the show ended Shatner just walked away. He didn’t try to keep in touch with the others, he really tried to leave Trek behind. Admittedly he had a lot of other issues, being type cast really hurt his career, he went through a nasty divorce. But the rest of the cast was kind of bitter about it. The movies kind of brought them back together again, but he still kept some separation. After DeForest died he started changing on that front, he also went on a bit of a path to try to understand Trek from a fan perspective. For the most part he gets along with the cast now, except Takei, whose name he still doesn’t pronounce correctly and George just doesn’t like him.
