The principal quantum number, n, designates the main energy levels occupied by electrons. The number of orbitals in an energy level is n2 (n squared), so that the first energy level, n = 1, contains 1 orbital; the second energy level, n = 2, contains 4 orbitals; the third energy level, n= 3, has 9 orbitals; and the fourth energy level, n=4, has 16 orbitals, and so on.
principal quantum number
Quantum numbers specify the orbitals in an atom. The set of numbers that cannot occur is n=3,I=3, m(sub)I=2 because there are no F-orbitals.
The answer would be an electrons position cannot be known precisely.
Pauli's exclusion principle
By azimuthal quantum numbers.

For fun, let's give them numbers instead of letters, and call s "0", p "1", d "2", and f "3".Then the number of distinct orbitals for any given principal quantum number (which is a more precise way of the concept you meant when you said "energy level") is twice the number plus 1... though the principal quantum number must be higher than the numbers we just gave the orbitals in order for there to be any at all (there aren't any 1p orbitals, for example). For principal quantum number of at least four, there are 1 s orbital, 3 p orbitals, 5 d orbitals, and 7 f orbitals. If we call the four quantum numbers n, l, m, and s, where n is the principal quantum number, l is the azimuthal quantum number, m is the magnetic quantum number, and s is the spin quantum number, the permissible values are: n - any integer such that 0 < n ("shell") l - any integer such that 0 <= l < n (orbital "type" - s, p ,d ,f, g, h, i, etc.) m - any integer such that -l <= m <= l (individual orbitals of type l) s - -1/2 or +1/2 (electron "spin")
