I have a steel bin with junk, and a big part of it are thread forming
dies that are rectangle shaped. I am curious what are they usually
made of. A2/D2 or HSS?

If you're talking about cylindrical thread-forming dies, they're high-end HSS (usually M4 or above). If they're flat dies for cold-rolling, D2. Hot-rolling dies are other tool steels; I forget which.
