The first quantum number (n) represents the energy level (shell), so for a 1s2 electron, it would have a value of 1.

It's the azimuthal quantum number. It specifies the angular momentum of the orbital, which can broadly speaking be thought of as its "shape." (The reason I'm putting that in quotation marks is that it's possible for two orbitals with the same azimuthal quantum number to appear rather different in overall shape.)

The shape of the electron cloud is determined by the secondary quantum number. The first is n, or the energy level, the second is the sublevel, the third is the specific cloud, and the fourth is the spin.
n = 3
