Refrigerants release CFC's. They react with ozone to deplete it.
"Freon" is a trademark name of DuPont for a series of HFC and CFC refrigerants which they manufactured - other companies manufactured and continue to manufacture the same refrigerants, but cannot use the name Freon for their product. Some of the refrigerants marketed under the name Freon are flammable, and some are not. The CFC refrigerants will almost certainly be flammable - the HFC refrigerants may or may not be.
