Can it be confirmed that these are fire resistant? I received the item and there was no product information.

They’re sound proof not fire proof.

I’ve now tried 5 times and want to loose my mind to attach them to a ceiling. What do you recommend?

Honestly - staple gun. Adhesives don’t work well on this material.

Two question are these all black? and are these 1" or 2" in thickness - your description states both 1" and 2" which is it ?

You can order 1" or 2". I suggest 2", the 1" are crap

Will these help absorb the stomping vibrations from upstairs neighbors?

It didn't help for me, 12 pc of these is really not a lot of coverage. It only helped absorb a small amount of noise from room to room
