Measurement of the branching fractions of $D^{+}\to K^{+}{K}^{-}{\pi }^{+}{\pi }^{+}{\pi }^{-}$, $\phi {\pi }^{+}{\pi }^{+}{\pi }^{-}$, $K_S^0{K}^{+}{\pi }^{+}{\pi }^{-}{\pi }^0$, $K_S^0{K}^{+}\eta$, and $K_S^0{K}^{+}\omega$ decays

Using $20.3{\mathrm{f}\mathrm{b}}^{-1}$ of $e^{+}{e}^{-}$ collision data collected at a center-of-mass energy of 3.773 GeV with the BESIII detector operating at the BEPCII collider, the branching fractions of three hadronic charm meson decays, $D^{+}\to \phi {\pi }^{+}{\pi }^{+}{\pi }^{-}$, $D^{+}\to K_S^0{K}^{+}{\pi }^{+}{\pi }^{-}{\pi }^0$, and $D^{+}\to K_S^0{K}^{+}\omega$, are measured for the first time to be $(0.54\pm 0.19\pm 0.02)\times {10}^{-4}$, $(2.51\pm 0.34\pm 0.14)\times {10}^{-4}$, and $(2.02\pm 0.35\pm 0.10)\times {10}^{-4}$, respectively. Futhermore, the branching fractions of $D^{+}\to K^{+}{K}^{-}{\pi }^{+}{\pi }^{+}{\pi }^{-}$ and $D^{+}\to K_S^0{K}^{+}\eta$ are measured with improved precision, yielding values of $(0.66\pm 0.11\pm 0.03)\times {10}^{-4}$ and $(2.27\pm 0.22\pm 0.05)\times {10}^{-4}$, respectively.
