2nd game: Could be one of two games, which look very similar, so I'm not sure and won't guess.
3rd game: It's the Ancients' dance, where they teach the code to open one of the doors on Mars. The masked guy is the Shaman in Zaire. (Zak McKracken and the Alien Mindbenders)
4th game: Armakuni, in the chambers of fire (Last Ninja 3)
