This paper reports measurements of processes: e{sup +}e{sup -}{yields}{gamma}K{sub S}{sup 0}K{sup {+-}}{pi}{sup {+-}}, e{sup +}e{sup -}{yields}{gamma}K{sup +}K{sup -}{pi}{sup 0}, e{sup +}e{sup -}{yields}{gamma}{phi}{eta}, and e{sup +}e{sup -}{yields}{gamma}{phi}{pi}{sup 0}. The initial-state radiated photon allows to cover the hadronic final state in the energy range from thresholds up to {approx_equal}4.6 GeV. The overall size of the data sample analyzed is 232 fb{sup -1}, collected by the BABAR detector running at the PEP-II e{sup +}e{sup -} storage ring. From the Dalitz plot analysis of the K{sub S}{sup 0}K{sup {+-}}{pi}{sup {+-}} final state, moduli, and relative phase of the isoscalar and the isovector components of the e{sup +}e{sup -}{yields}KK*(892) cross section are determined. Parameters of {phi} and {rho} recurrences are also measured, using a global fitting procedure which exploits the interconnection among amplitudes, moduli, and phases of the e{sup +}e{sup -}{yields}K{sub S}{sup 0}K{sup {+-}}{pi}{sup {+-}}, K{sup +}K{sup -}{pi}{sup 0}, {phi}{eta} final states. The cross section for the OZI-forbidden process e{sup +}e{sup -}{yields}{phi}{pi}{sup 0}, and the J/{psi} branching fractions to KK*(892) and K{sup +}K{sup -}{eta} are also measured.
