What happens when আপনি cut off a ভ্যাম্পায়ার limb. Does it turn to dust is it just gone does it regenerate???

Basically the vampire is still alive

I'm not sure. Maybe the vampire can reattach the severed limb, assuming he অথবা she can still find it. Maybe the vampire grows a new limb. I don't think he অথবা she would be stuck without a limb permanently though.
