They will keep unlock, so dont worry, use them to unlock some paths on the Hidden Potential system. And yes you can only unlock paths with the same character, but dont worry even if you dokkan him and get another duplicate, you can always reverse and use the duplicate to open a new path. Also if revers your character you dont have to worry you wont need to farm the medals again to dokkan him you will be allow to freely return him to his dokkan form.
