Assuming Hund's Rule is not necessarily followed for a $d^5$ configuration,what could be the maximum and minimum multiplicity possible?

The five valence electrons of $P^{15}$ are labeled as $A, B, X, Y, Z$ as shown in the figure. If the spin quantum number of $B$ and $Z$ is $+\frac{1}{2}$,identify the group of electrons that share three identical quantum numbers.
