While 7 is pushing the upper limits, the main concern should be "what will the outlets be running?

If you're putting a freezer out there, it should probably be on a separate circuit.

If you'll be running any high amperage equipment; again, put it on a separate circuit.

What is a dedicated circuit?

A "dedicated" circuit is one to which only one device is or can be connected; therefore the circuit is "dedicated" to the device. A NON dedicated circuit will therefore be one to which multiple devices can connect, such as the wall outlets in your home. Multiple wall outlets are connected to a common circuit breaker, making that an example of a non-dedicated circuit.

How many wall outlets can you have in a circuit using a A breaker?

Assuming this is not an office of a place where lots of the outlets will be used to power items that draw lots of current on a 15 amp circuit wired with 14/2 wire I would limit it to no more than 10 outlets and lights combined. On a 20 amp circuit wired with 12/2 wire I would limit it to a 14 outlets and lights combined. There is no limit in the code. You just use common sense based on what is going to be used on this circuit.
