More RPG maker questions

Is it possible to use .avi or .mpg files as FMVs for games made with an RPG Maker? Is it also possible to have about 7 characters per party? Can you make the game have multiple endings? Is it also possible to make a little mini game where you can freely make a character move and attack in real time?

Which version?

In RM2k, you can have .mpg and .avi play. Only four characters per party, though.

The other ones are only limited to your scripting ability, neither of which seem too difficult to pull off.
