Yes
All light aircraft (at the very least all CofA aircraft - I don't know about PFA) have to be spin tested and have to exhibit more or less normal spin characteristics. The exact anti-spin procedure is in the POH. So you should be able to stop the spin even in aircraft that are not authorized to be spinned with an established procedure, usually by unloading the elevator and applying opposite rudder.
Yes, but no but yes but.... The spin testing only requires recovery after half a turn if the aircraft is certified as "spinning not allowed". Thus if it goes beyond a half turn you become the test pilot.
