Will these fit a 12oz SS coffee mug?!

These are meant to fit a "Corny" keg used mostly by homebrewers these days. The lid opening on that is about 4 inches by 2 ¾ (that is a rough guess). They are also quite think at about ⅜ of an inch. The smaller gaskets are maybe ½ inch and smaller.

Will these work on a firestone keg?

Yes. I used this to replace gaskets in one of my Firestone kegs. Make sure you get a tube keg lube and give the gaskets a light coating when you install them.

Weird question, I know, can these go in the oven/withstand heat?

Thank you for your question, it can not be put into the oven.
