Its Principal quantum no is 2
The principal quantum number refers to the electron shell, or energy. Refer to the related link to read a Wikipedia article about quantum numbers.
secondary quantum numberI don't think it is a number, but it could be referring to the Orbitals, being S, P, D, and F. Each orbital is a specific shape and the orbitals are determined in blocks on the Periodic Table. The energy, or Quantum Number would go in front, such as 4p, which means the principal quantum number or energy level is 4 and the orbital shape is p. Hope this helps
Yes, quantum numbers define the energy states and the orbitals available to an electron. The principal quantum number (n) determines the energy level or shell of an electron, the azimuthal quantum number (l) determines the shape or orbital type, the magnetic quantum number (m) determines the orientation of the orbital, and the spin quantum number (+1/2 or -1/2) determines the spin state of the electron. Together, these quantum numbers provide a complete description of the electron's state within an atom.
By the first principle energy level I assume you are referring to the lowest atomic orbital or ta principal quantum number of 1. This orbital holds 1 pair of 2 electrons.
n
The quantum number relating to the size and energy of an orbital
Its Principal quantum no is 2
by the quantum number n. if n=1 energy level is at 1 if n=2 energy level is 2 for example 2s1

nothing at all, because the s orbital is a spherosophical orbital, while the principal energy level isn't.

n is the first quantum number. It is the principle quantum number. It refers to what energy level it is and will be one greater than the number of nodes in the orbital. l is the second quantum number. It is the angular momentum quantum number and refers to the shape of the orbital. ml is the third quantum number. It is the magnetic quantum number and it refers to the orientation of the orbital. ms is the fourth quantum number. It is the spin quantum number and refers to the magnetic character of the orbital.
