I would like to overstock my 55, it is going to be a fish only tank, and I only want yellow tangs. How many can I have?

Why would you want to do that?

A single one in a 55 gal tank is more than enough. It's borderline at best if the yellow tang is small, and I would even say it's small for any tang. They are VERY active swimmers, needs lots of space.
But in any case, you cannot talk about more than one tang in a 55, sorry for the news. But there are plenty of other nice fish to choose from.
