The minimum number of quantum numbers required to specify an orbital in an atom is

The two electrons $X$ and $Y$ have the following sets of quantum numbers:

$X: n=3, l=2, m=-2, s=+1/2$

$Y: n=3, l=0, m=0, s=+1/2$

Which of the following is the correct statement?

Five valence electrons of $P^{15}$ are labelled as $\boxed{AB}_{3s} \,\boxed{X|Y|Z}_{3p}$. If the spin quantum numbers of $B$ and $Z$ are $+\frac{1}{2}$,the group of electrons with three of the quantum numbers $(n, l, m)$ the same are:

The energy required to remove an electron from different subshells of a $H$ atom is given below. What is the order of these energies?

Correct statements for an element with atomic number $9$ are:
$A.$ There can be $5$ electrons for which $m_{s}=+\frac{1}{2}$ and $4$ electrons for which $m_{s}=-\frac{1}{2}$
$B.$ There is only one electron in $p_z$ orbital
$C.$ The last electron goes to an orbital with $n=2$ and $l=1$
$D.$ The sum of angular nodes of all the atomic orbitals is $1$
