Q: solid and plain とはどういう意味ですか?
A: Sam: Do you like him?
Jill: I don't know, his personality is kind of plain..
in this situation, calling his personality "plain" is similar to saying it doesn't stand out. Jill is saying he has a very boring personality.

Sam: Do you like him?
Jill: Yes, his personality is very solid.
It's very common for solid to be used as a good thing when referring to someone. In this case, Jill is saying that his personality is good and he doesn't have many flaws in his personality. You can relate this to someone saying a structure is solid, meaning the structure is sturdy and most likely won't cause any trouble, like collapsing.
Does this help you understand better?
