Hund's Rule and Pauli's Principle
In Hund's Rule, one electron moves into each of two or more degenerate (i.e. same energy) orbitals until all of them are half full before pairing up. You may have heard it before in reference to the example of filling seats on a bus: everyone finds their own seat, and they only start sitting together after all of the seats are half full in filling electrons.
According to the Pauli Exclusion Principle, no two electrons can be identified using the same quantum numbers. We have the spin quantum number because it ensures that two electrons in the same orbital have different quantum numbers of electrons.

Answer:
Hund's Rule states that if 2 or more degenerate (i.e. same energy) orbitals are available, one electron goes into each until all of them are half full before pairing up . ... The Pauli Exclusion Principle states that no two electrons can be identified by the same set of quantum numbers.
What is the principle of Hund's Rule?
Hund's rule states that: Every orbital in a sublevel is singly occupied before any orbital is doubly occupied. All of the electrons in singly occupied orbitals have the same spin (to maximize total spin).
