Answer 1

Is there a way to not only connect 2 devices via WiFi Direct but also three or more?

Yes, the Wi-Fi Direct specifications explain it is possible to create a 1 to many connection. One of the devices will act as a group owner (think it as an access point). I have been able to create a Wi-Fi Direct network with 3 devices during some tests.

As all the devices have to be in the range of the group owner, you are sure that your message will arrive to the second client. 1st client -> group owner -> 2nd client
