    NS6
    P2S6
    C?
    Phosphorus tetrabromide

    Need to correct response by Anon.

    Penta means 5
    tetra means 4
    nitrogen pentasulfide would be, following the name, NS5. I haen't heard of this compound. I would expect a N/S compound to be N2S5 (simiilar to P2S5 in the next compound); however, I assume that name would be dinitrogen pentasulfide.
    Diphosphorus pentasulfide is P2S5.
    AS2S3 doesn't mean a thing to me. You may have made a typo and it should have been written as As2S3. That compound is diarsenic trisulfide.
    PBr5 is phosphorus pentabromide.
