I think that most people would just say that there are cardinal and ordinal numbers. I've read somewhere about "nominal" numbers (numbers that name something like a number on a sports jersey or something like that), but I don't know how conventional that is. In a mathematics class, we talk about real numbers, rational and irrational numbers, integers, whole numbers and natural or counting numbers. Those are probably not practical or "every-day" numbers that anyone but a math teacher would use..... :p

Algebraic, transcendental, imaginary, complex, surreal, ... But this is a different distinction from cardinal vs ordinal (in either sense - 3 vs 3rd or set-theoretic).
And I don't think many people talk about "quaternion numbers" (just "quaternions"), but computer games programmers use them a lot.
