    You mix up two different things: filter type (CPL vs. UV) and quality feature (Multi Coating).
    A bit reading can tell you that UV filters have no effect in normal photography, sensors are not sensitive to UV lights and in Singapore the amount of UV is fairly limited. The remaining purpose for UV is to give some people the feeling of protection for their lenses. Another side effect are filter flare and other funny reflections, usually unwanted.
    The purpose and function of a CPL is just explained above by Diavonex. Nothing to add.
    Multi-Coating is a form of surface treatment for filters to prevent reflections at the glass surface. Multi-coating is better than single coating or even uncoated.
    Vitacon is a brand known for it's substandard quaility. Have a look at Hoya for a decent quality level, regardless whether UV or CPL.

    , something to read.
    Technically you can stack filters (provided they have the same thread diameter), but not recommended. Filter stacking can cause vignetting or your CPL gets stuck on the UV. With cheap filters like your Vitacon chances are good.

    You can get a CPL filter but not really attach to your exisiting filter coz it might cause vignetting

    That's a consensus here in forum. For price indications please check the Price Guide. Prices for filters don't change much. Alternatively you can also check the Mass Sales offerings.

    I'm using HOYA CPL; it'll cost you approximately $80 to $90 for 77mm.

    Filters are easily cleaned with a Lenspen irrespective of brands.
