I know that for most elements, they need 8 electrons and helium needs 2 in the outer energy level to become stable. How about hydrogen (H)?

Two - because the first level can only hold two electrons.

Hydrogen has an atomic number of 1, thus 1 proton and 1 electron. Unlike other elements in the first group that need to follow octet rule in order to have a stable outer energy of 8 electrons, Hydrogen need to have only 2 electrons. Thus, as it has only 1 electron, it still need 1 extra electron in order to have its outer energy level stable.

Hydrogen is the same as Helium, stable with 2 electrons

I believe it's two.
