How do I access a class in wordpress?

"class WP_User" is in wp-includes folder,
my php is in wp-admin folder,

if I just do new WP_User($id), it says class not found. if I use "include" I would basically copy the whole thing over?
how do I do this?

I don't know about Wordpress specifically, but in general, to use a class in PHP the class definition must be included first.

If you know where you class file is, and Wordpress doesn't have an autoloader set to load it automatically, then you could simply "include" the file.
