I don't have a full list, but I do have an explanation. Here's from an interview with Chris Jericho
"You know when we had the 'Order of the Black' … it's what is the order? What is the Black Label order? It's a religion and yes we're all confused and nobody knows what's going on and everyone seems to be happy. But you know, cause I'm Catholic, so the whole thing is the running joke would always be that any of our brothers that are Jewish, like Adam who engineers the records, is our favorite Irish Catholic Rabbi engineer. So it's a sight, and nobody knows what's going on, but we all seem to be happy. So yeah, it's because I'm Catholic and it's a running joke, so it's Father this and Father that. And there are all the guitar players that we love and musicians, and so obviously anyone who has passed away has gone into sainthood, so it's Saint Rhoads, Saint Hendrix and stuff like that. And obviously Jimmy Page hasn't passed, but he's his own religion anyways, but he's the pontiff. You have Pope Page … so that's the running joke we have going."

So basically everyone is Father. If they pass away then they are Saint. With a few exceptions, I suppose. Ozzy, for example, is just "The Boss".

I stopped scrolling Instagram to type this and get back to work but I think you get the idea.
I've always loved that he does this. It's so strangely wholesome but in just the goofiest way.
