I need to know what those things for lathes are called that cut non cylindrical holes.
i think like a kind of jig with a shaped hole mounts on the object, and then a chisel-like thing goes in and shapes the hole in the object youre cutting into a square, hexahon, etc. (whatever shape the hole in the jig is.)

They are called broaches and they don't get used with lathes (because they don't rotate to cut). They are typically used with presses that push them into the material to be cut so that progressive teeth on the broach cut more and more of the desired profile into the hole. When the broach hits the bottom of the material with its last teeth you have the exact shape you are aiming for (usually no secondary operations needed).
btw a reamer also rotates (to clean up an ordinary drilled hole into a perfectly-precise round hole).

Hmmm, definitely not a lathe. A reamer may be the machine name you're looking for.
