For the 1st electron, n=4, l=2, m=1, s=+½

the electron is in 4th shell, d subshell, and having a clockwise spin. (4d)

for 2nd elcetron, n=4, l=1, m=1, s=+½

so, elcetron is in 4th shell, p subshell and having a clockwise spin. (4s).

elcetron in 4s subshell has lower energy than 4d subshell. Both have same spin. and are present in same shell
