He is very goofy and musical.

Charlie
Charlie is Lucifer's daughter. It's unknown what their relationship is outside of being blood related.

In her VIVZIE STREEM- Test Test -#1 live stream, when asked if she can tell fans anything about Lucifer or at least what his relationship is like with Charlie, Vivziepop said that she can not say very much about Lucifer because of it unfortunately being a little bit too much of a spoiler for the future (especially his relationship with Charlie, which is actually kind of a big part of the show).

According to Vivziepop in YouTuber ARTISM PODCAST Artism Episode 59: VivziePop podcast, Charlie takes very much after her dad.

Lilith
Lilith is Lucifer's wife. It's unknown what their relationship is outside of being married.
