how can I add ringtone in this folder " system/media/audio/ringtone/"
have you really set up a google account? Check it under Settings -> Account & Sync

Cou can add ringtones in this folder by copying your ringtone files in the flashable zip file in that folder so the ringtones will be flashed with the rom, or you can push them to your phone via adb
