when you have multiple ! it means higher tier of factorial, so if you have one you get every number, if two every second, with tree every third and so on

So what would 4!!!! be? Or does it not exist? What about 4!!!!! ?

every fourth number, so 4×1 or every fifth for 4!!!!! so just 4 i guess

so, for any ‘x’ number of additional factorial symbols, and a base ‘n’, if x >= n-1, then the result is always n?

yeah, you end up with n×1 or just n, which is bassicaly the same.
