The codelab is designed as a showcase of only two connections.

If you want a code focused on multiple connections, perhaps you want to have a look at the webrtc/samles where they have an example of multiple peer connections.

As for adapting the codelab:

Assuming you are on step-06, the lines of code that relates to the limit of users per room are these:

index.js [36-49]:

    if (numClients === 0) {
      socket.join(room);
      log('Client ID ' + socket.id + ' created room ' + room);
      socket.emit('created', room, socket.id);
    } else if (numClients === 1) {
      log('Client ID ' + socket.id + ' joined room ' + room);
      // io.sockets.in(room).emit('join', room);
      socket.join(room);
      socket.emit('joined', room, socket.id);
      io.sockets.in(room).emit('ready', room);
      socket.broadcast.emit('ready', room);
    } else { // max two clients
      socket.emit('full', room);
    }

Here, you can change the number of peers that you want to interact together:
} else if (numClients === 1) {

If you want to remove the limit, you can simplify the if statement.

    if (numClients === 0) {
      socket.join(room);
      log('Client ID ' + socket.id + ' created room ' + room);
      socket.emit('created', room, socket.id);
    } else {
      log('Client ID ' + socket.id + ' joined room ' + room);
      // io.sockets.in(room).emit('join', room);
      socket.join(room);
      socket.emit('joined', room, socket.id);
      io.sockets.in(room).emit('ready', room);
      socket.broadcast.emit('ready', room);
    }

If it does not work, perhaps other changes are required. In this case, I recommend you that you complete the codelab to learn the basics; then, you can base your efforts on the multiple peers sample from the other repository.

I hope this helps.
