Lucchese- John Campopiano
Gambino- Frank Basto, there are a few more.
Genovese- Louis Arminante
Colombo- Vincent Aloi
Bonanno, I think there is really no one left. They all died out. It is possible that maybe one or two might still be alive that we never heard of.

John (Johnny Echoes) Campopiano died October 7, 2018
Frank (The Bear) Basto died April 14, 2018
I couldn't find any specific death date for Louis (Gigi) Arminante, but I believe he's gone too.
The only one of the four mentioned that I know is still alive is Vinny Aloi.
