I don't think any of the Avengers could wield Thor's hammer,other than Thor himself.Hulk tried to in the first movie,but couldn't.I think the other Avengers would experience the same result.They even had a scene in Avengers Age of Ultron trying to see who could wield Thor's hammer.There was someone,other than Thor,who was able to wield it(but will not spoil it for those who haven't seen it)
I am always for captain America. but here we see Steven rogers (cap America) unable to lift Thor's hammer. So I think no one in avengers can lift it. IRON FIST, who is not an avenger, can lift the hammer.
