Using 383x10{sup 6} BB pairs from the BABAR data sample, we report results for branching fractions of six charged B-meson decay modes, where a charged kaon recoils against a charmless resonance decaying to KK* or {eta}{pi}{pi} final states with mass in the range (1.2-1.8) GeV/c{sup 2}. We observe a significant enhancement at the low KK* invariant mass which is interpreted as B{sup +}{yields}{eta}(1475)K{sup +}, find evidence for the decay B{sup +}{yields}{eta}(1295)K{sup +}, and place upper limits on the decays B{sup +}{yields}{eta}(1405)K{sup +}, B{sup +}{yields}f{sub 1}(1285)K{sup +}, B{sup +}{yields}f{sub 1}(1420)K{sup +}, and B{sup +}{yields}{phi}(1680)K{sup +}.
