Basically the operators are just analogous to the classical ones e.g. the classical:
becomes:

Besides the angular momentum in each direction, we also have the total angular momentum:
🔗
Then you have to understand what each one of those does to the each atomic orbital:

There is an uncertainty principle between the x, y and z angular momentums, we can only measure one of them with certainty at a time. Video 71. ""Quantum Mechanics 7a - Angular Momentum I" by ViaScience (2013)" justifies this intuitively by mentioning that this is analogous to precession: if you try to measure electrons e.g. with the Zeeman effect the precess on the other directions which you end up modifing.
