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

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^0_SK^+\pi^+\pi^-\pi^0

, and

D^+\to K^0_SK^+\omega

, are measured for the first time to be

(0.54\pm0.19\pm0.02)\times 10^{-4}

,

(2.51\pm0.34\pm0.14)\times 10^{-4}

, and

(2.02\pm0.35\pm0.10)\times 10^{-4}

, respectively. Futhermore, the branching fractions of

D^+\to K^+K^-\pi^+\pi^+\pi^-

and

D^+\to K^0_SK^+\eta

are measured with improved precision, yielding values of

(0.66\pm0.11\pm0.03)\times 10^{-4}

and

(2.27\pm0.22\pm0.05)\times 10^{-4}

, respectively.
