I was not trying to be cute, I'm not sure I know them, but here goes.

Bennett - Sahara
Binion - Horseshoe
Boyd - Stardust I guess, thats where the dinner is.
Englestad - Imperial Palace
Frettita - Stations - My guess is Palace Station - but only a guess
J. Gaughn - El Cortez is my guess
M. Gaughn - Orleans again a guess
Hilton - your guess is as good as mine
Kirkorian - MGM
Marnel - Rio
Redd - Si Redd's - Is that the name of his casino?
Maloof - Fiesta

I will see the art work in a few days and will fill in the blanks.
