Was he the janitor in Billy Joel's For the Longest Time music video?

Was Bill Cobbs that guy who was in the movie The Derby Stallion with Zac Efron? That movie was the first time I saw Bill Cobbs act and he played the horse trainer in The Derby Stallion and Bill Cobbs also was in The Bodyguard too

Very sad.......

Wasn’t he the man who Bookman was showing the Evans’ apartment to in the “Evans Versus Davis” episode of Good Times? Anyways, RIP to him. :(

Was he the janitor in Billy Joel's For the Longest Time music video?

After some searching, I found that the janitor was Nick Stewart who was mostly known from "Amos 'n' Andy".

Yes to the other "Was he the guy from..." questions.
