finding the Right hand side of an object

Suppose l want to position something to the right of a game object. | can find the game object and in transform it has a Right property that represents this access but I'm not sure how to use it. I'm assuming I have to use the difference between local and world coordinates but can it quite figure out how so same pointers would help.

Once I've done that I want to be able to position to the right in front of and above an object...

Any hints gratefully recieved
