Also not an Angola owner, but my guess: (8) either your dash air, or switch to activate cruise air, if you have bus air. (9) Can't read the button. (10) Switch for your back up camera to engage your back up camera when trans is in reverse, or to keep camera on at all times. (3) Can't read. (4) Can't read. (5) engage/disengage your back up alarm when in reverse.
Will be interesting to hear the results.
