Answer
Both situations are possible.
Work Step by Step
The electrons might have the same principal quantum number n, but have different orbital quantum numbers, l. Their orbital angular momenta would be different. As a concrete example, consider an electron in the 2s state in one atom, and an electron in the 2p state in another.
