I'm not sure about what you ask here.
Do you want to know how to add several animations to a sprite, importing frames from a sprite sheet ?
If so, when you're done with the procedure in that page of the tutorial, right click the "Animations dialog"

And select "Add a new animation".
From there you'll be able to import again frames and have a new animation usable in your sprite.
As Ashley said, if you want, in events, to display another animation of your sprite, use the sprite action "Set animation".
Does that answer your question ?
Maybe a little read through the manual could help you up picking the vocabulary and ways of working with C2.
