You cannot change to F-1/F-2. You must either seek to change to F-1 or F-2. Whether you can or should reapply depends upon why you were denied and your current nonimmigrant status. You should schedule a consultation with an experienced immigration attorney. You can read more about student visas at http://myattorneyusa.com/student-visas.
