Using data samples of $89{\mathrm{fb}}^{-1}$, $703{\mathrm{fb}}^{-1}$, and $121{\mathrm{fb}}^{-1}$ collected with the Belle detector at the KEKB asymmetric-energy $e^{+}{e}^{-}$ collider at center-of-mass energies 10.52 GeV, 10.58 GeV, and 10.876 GeV, respectively, we study the exclusive reactions $e^{+}{e}^{-}\to \omega {\pi }^0$, $K^{*}\left(892\right)\overline{K}$, and $K_2^{*}\left(1430\right)\overline{K}$. (Charge-conjugate modes are included implicitly.) Significant signals of $\omega {\pi }^0$, $K^{*}(892{)}^0{\overline{K}}^0$, and $K_2^{*}(1430{)}^{-}{K}^{+}$ are observed for the first time at these energies, and the energy dependencies of the cross sections are presented. On the other hand, no significant excesses for $K^{*}(892{)}^{-}{K}^{+}$ and $K_2^{*}(1430{)}^0{\overline{K}}^0$ are found, and we set limits on the cross section ratios $R_{\mathrm{VP}}=\frac{{\sigma }_B(e^{+}{e}^{-}\to K^{*}(892{)}^0{\overline{K}}^0)}{{\sigma }_B(e^{+}{e}^{-}\to K^{*}(892{)}^{-}{K}^{+})}>4.3$, 20.0, and 5.4, and $R_{\mathrm{TP}}=\frac{{\sigma }_B(e^{+}{e}^{-}\to K_2^{*}(1430{)}^0{\overline{K}}^0)}{{\sigma }_B(e^{+}{e}^{-}\to K_2^{*}(1430{)}^{-}{K}^{+})}<1.1$, 0.4, and 0.6, for center-of-mass energies of 10.52 GeV, 10.58 GeV, and 10.876 GeV, respectively, at the 90% C.L.
