WiFi-Direct or Wi-Fi Peer to Peer can do multiple device connection.

See this link to read more about P2P connections -https://developer.android.com/training/connect-devices-wirelessly/wifi-direct.html

WiFi-Direct automatically select which device will be the Group Owner or the server base on which device is the most compatible to be the Group Owner or the server. But you can manually select which will be the Group Owner by setting WifiP2pConfig groupOwnerIntent = 15(the highest value).

If two devices are connected, when you connect another device this device will connect to the group owner(or server).

For you to able to send streams to client devices you can use java Sockets. When peer to peer connection is established, the group owner will be the one to handle the server socket and client socket for the client devices.

If you have multiple devices and you want to send a message to a specific client device you'll send it to the server and the server will send it to the specific client. see this link - WiFi Direct (Android 4.0) with multiple (3+) devices
