Correct statement(s) among the following is/are

Magnetic quantum number distinguishes between the orbitals available within a subshell.

The restrictions on principal quantum number (n), azimuthal quantum number (l), magnetic quantum number (m)  and magnetic spin quantum number  $\left(m_s\right)$,  give rise to  $2n^2$  sets of quantum numbers  for every value of n, the principal quantum number. 

Magnetic spin quantum numbers,  $m_s=\pm \frac{1}{2}$  refer to two quantum mechanical spin states and, are independent of other three quantum numbers.

The restrictions on azimuthal quantum number (l) and magnetic quantum number, (m) give rise to $n^2$  sets of quantum numbers for every value of (n), the principal quantum number.
