The word "alien" has more than one definition. By space aliens, then we don't know, because no one's a 100% sure if space aliens exist yet. However, by aliens, as in people from different countries, then they should have 2 hands with 5 fingers on each hand.
Multiple fingers on an aliens hand is possible, but no one can know for sure until they meet one.
