A Xenomorph might be friendly if it formed a symbiotic relationship. For example, if it realized that by working with other species, it could get more food or better living conditions. Say there was a planet where the Xenomorphs and another species both needed a certain resource. Through cooperation, they could both thrive, and the Xenomorphs could become friendly towards the other species over time.
A friendly Xenomorph might have less menacing features. Instead of its usual sharp, menacing claws, they could be shorter and less pointed. Its body color could be more muted, not the typical dark and intimidating color. Maybe it would have a more rounded shape rather than the angular, scary form it usually has.
