The polarization dependence of $2p \to 3d \to 2p$ resonant X-ray emission spectroscopy (RXES) in $3d^{1}$, $3d^{2}$ and $3d^{3}$ systems (TiF3, VF3 and Cr2O3, respectively) is measured and analyzed by means of the MX6 (M denotes a transition metal and X denotes a ligand, respectively) cluster model. The results are compared with a previous one for the $3d^{0}$ system (TiO2). Generally, with increasing $3d$ electron number, the spectral structure of RXES becomes more complicated by the influence of the crystal field and the multiplet coupling effect. Moreover, we point out that the selection rules on the polarization dependence of RXES change with the $3d$ electron number and that a drastic resonance enhancement corresponding to the excitation to an antibonding state in the $3d^{0}$ system is almost absent for the $3d^{n}$ systems with $n = 1$, 2 and 3.
