This paper reports measurements of processes: e{sup +}e{sup -} {yields} {gamma}K{sup 0}{sub s}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} 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{sup 0}{sub s}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{sup 0}{sub s}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.
