Hmmm... let's see.
Alien- The alien easily overpowers any human it encountered. It easily lifted a grown man off the ground. We really didn't see it's speed displayed.
Aliens- The aliens were very strong. They were breaking down the door when the humans were escaping. They were shown to be very agile by jumping all over the place. They were moving rather fast in air vents while chasing the humans. As for durablity, I think they were rather durable. The pulse rifles fire armor piercing, explosive rounds. I don't think anything could last long against that. The alien that got the drop on Vasquez was still kicking even after having a few rounds placed in it's head at point blank. The shots fired by Gorman just bounced off the one he shot at.
Alien 3- Once again, the alien makes short work of anyone it got it's hands on. It had ten tons of molten lead poured on to it. That means it can survive temperatures of at least 621.43 F. While it was outran throughout the film, it was shown to be able to run at extreme speeds.
Alien Resurrection- Like in Aliens, they were shown to be able to break down steel doors. They can also survive liquid nitrogen, which is -346 F. The aliens weren't really shown running in the film.
AvP- An alien can effortlessly lift and throw a Predator with it's tail. It could also fight, pin one down, and bite bite through it's mask. They were also shown running and it appeared to be fast.
AvP:R- Um, yeah... I got nothing to say.
Overall, Xenomorphs are shown to be extremely strong, durable, and fast. I think the 2010 AvP game was the closest of the games to display these traits. In that game, they run at 14 m/s (31 mph) and sprint at 28.47 m/s (63 mph), can take some damage, and easily over power humans.
