Hello Sunita - There are quite a few different island-type alcohol drinks that use combinations of pineapple juice, orange juice, coconut milk - most of them use rums, either light, dark, golden rums.

Probably the most well known one is the Pina Colada, which I'm sure you could put in a search and get the exact proportions.

There is also a drink called Pusser's Pain Killer, which uses all of the above ingredients and using Pusser's Golden Barbados Rum. It's yummy, too!

I'm sure other people will have additional ideas here.
