We just learned how to say Hello, Goodbye and Good Morning in ASL.
If you want to say How are you? in ASL, you start with how.
The hand shape you start with is like the "Bent B".
(from: wiktionary - appendix:sign language handshapes)
It's like the Bent B, but not exactly the same.
Keep your thumb up, bend your hand, point your fingers down, and your palm is facing down.
You do this with both hands, have them meet in front of you with the backs of your fingers facing each other.
Then rotate your hand at the wrist, bringing your fingers up toward the inside of your body until they are pointed up.
After that make the hand shape for "1" with your index finger, and point at the person you're talking to.
A lot of ASL also uses your face and your body, so it helps if you lean forward to show that you are interested in how someone is.
Here is a helpful video showing this sign, and also a way to say "What's up?" that you might say to your close friends:
