We　show　that　polarization　properties　of　the　suppression　and　enhancement　as　well　as　the　Autler-Townes　(AT)　splitting　of　two　coexisting　six-wave　mixing　(SWM)　processes　in　multi-Zeeman　levels　atomic　system.　By　scanning　the　frequency　detuning　of　the　dressing　field,　we　observe　the　suppression　and　enhancement　as　well　as　the　AT　splitting　of　the　two　coexisting　SWM　processes　with　the　different　polarized　probe　beams.　Different　polarization　states　of　the　probe　beam　can　select　different　transitions　among　multi-Zeeman　levels　and　different　dressing　strengths.　The　AT　splitting　separations　get　slightly　large　as　the　probe　beam　changes　from　the　linearly　polarized　state　to　the　circularly　polarized　one.　Under　the　conditions　of　different　dressing　fields,　the　polarization　dependence　of　the　SWM　enhancement　and　suppression　shows　the　inverse　variation.　Theoretical　calculations　are　carried　out,　which　are　in　good　agreement　with　the　experimental　results.
