Yes it is
On the Astral you can interact just like you can in the Physical plane.
You can shake hands, fight, hit each other but unknowingly if the two persons happen to bump each other then they will pass through the other.
Hope that I was of help to you.

Actually yes,when I was in the astral state I went with some people to climb race a fountain,I don't know about physical/astral interaction though,since my memories are still quite foggy from my experiences.
It is possible by all means. However since you're not speaking with a physical voice you have to appeal to their mental perception rather than their physical ears. For instance bonds work very nicely, that and body language. Get creative, there's a lot you can do.
