I see four pinball machines in the pictures, but the seller only mentions two of them, the Ballys. The seller mentions an Elvis pin, but it is probably a Brunswick Alive that isn't worth anything, but it could be a Stern Elvis. I think that I have the right editions of the Fireballs based on their pictures.
