How to Increment a nvarchar value + number when more then one value is
displayed for a given ID

I need to add a address type value to a column when more then one value is
returned from the query below. For example if a single result is returned
then I want the value in the address type column to be Business. But if
there is more then one value returned, I want it to increment a value
after the first result to be Alternate Business 1,Alternate Business 2,
Alternate Business 3 etc.
Can anyone help me out?
