You can send messages to all users who has joined the room by:

io.of("/roomName").emit("eventName", "message");

for your case :

io.on('connection', function (socket) {

  socket.on('AllUsers' , function (data){
    console.log(data);
    customerId[socket.id] = data.userId
    socket.join("customer");
    io.of("/customer").emit("chat", "hi");
   });
});
