Dear student
Please ask only one question in one thread.

in the case of a 4f orbital, we have n=4.

The letters correspond to the angular momentum quantum number in the following way:

s : l = 0

p : l = 1

d : l = 2

f : l = 3

(Historical note: the origin of the letters is from spectroscopy and they refer to sharp, principle, diffuse, and fundamental, respectively)

TL;DR 4f means n = 4, l = 3
