About 3 of mine answer to their names (Eric will in fact come if you call anybody!).
They know 'get down!', usually for when they are sat on the warm cable box and blocking the tv.
And a double clap means they have to leave whatever room they are in instantly, which they are mostly pretty good at.
Except Gracie the Ninja Kitten who will run out then bounce off a wall and run back in again!!Im hoping she gets calmer as she ages but as a tortie thats probably not likely.LOL
