Its not quite black hole stuff, but valid questions.

: From what I understand, in a multiple electron atom, J the total angular momentum is the vector sum of the spin angular momentum and the orbital angular momentum. But what about a single electron atom (hydrogen), is the total angular momentum still equal to Lz plus Sz?

The total "z" component of J is equal to Lz plus Sz. i.e. Jz = Lz + Sz

:Also is the total magnetic dipole moment equal to the sum of muorbz plus musz?

The "total" is not just z components, it is: mtot = ml + ms
