That second building can only have one source of supply. None of the exceptions apply to your situation. The code does not permit you to run multiple general use branch circuits from one building to another.
225.30 Number of Supplies.
Where more than one building or other structure is on the same property and under single management, each additional building or other structure served that is on the load side of the service disconnecting means shall be supplied by one feeder or branch circuit unless permitted in 225.30(A) through (E). For the purpose of this section, a multiwire branch circuit shall be considered a single circuit.
Dam, Tom, Learn to read Shortcircuit already said that.
