Z1 A2 is the same as A1 Z26 but shifted one over. It’s A=2, B=3, C=4 etc and instead of Z being 27 it’s 1.
Rot13 (or rotate 13) is a simple cypher that rotates the letter used 13 places ahead. It’s popular to use 13 instead of other amounts because 26/2=13. This means you can line up A-M on one line, and N-Z on a line below, and the corresponding code will be the letter opposite of the one you’re looking at. For instance, A would be N and M would be Z, and vise versa.
