Multiple compiled sources are on the Wiki page. The project's official Instagram account in particular has posters confirming each individual luchador's identity (but isn't opening for me ATM for me for some reason).
* Los Señors Xibalba are indeed the Calaveras
* Nanahuatzin is Fugaz
* Hunahpú is Max Star
* Xbalanqué is Futuro (the honking great tiger tattoo kinda gives it away)
* Ucumu is Capitán Suicida
This goes for the other 7 pages (and counting) too, obviously.
