When electrons ocoupy different orbitals of the same sub-level, do they all have the same spin?

Only as single electrons in the orbitals of a partially filled sublevel.

Explanation:

An orbital can contain a maximum of two electrons with opposite spins. Each orbital in the same sublevel must have one electron with the same spin before a second electron with an opposite spin enters the orbital. When there are multiple orbitals in the same sublevel, such as the three "2p" orbitals, "2p"_x"p"_y"p"_z", each orbital receives one electron of the same spin. If there are more electrons than "2p"^3", the additional electrons will enter each "2p" orbital with an opposite spin.
