No
To make the sign fro "no" you pinch your middle and index fingers together with your thumb.
Yes
The sign for "yes" is made by making a fist and moving it up and down. This is like knocking on the door.
Please
The sign for "please" is made by placing your flat right hand over the center of your chest. Move your hand in a clockwise motion (from the observer's point of view, use a circular motion towards your left, down, right, and back up) a few times.
Thank You
