How to make a server reply after receiving a request/data

seems to work fine You are closing the socket on the client right after you sent the ID. You need to keep it open and wait for the server to send it's data, e.g.:
Socket socket = new Socket(AddressFamily.InterNetwork, ...);

// open and send ID

int dataAvailable = 0;
while (dataAvailable == 0 || dataAvailable != socket.Available)
{
    dataAvailable = socket.Available;
    Thread.Sleep(100); // if no new data after 100ms assume transmission finished
}

var data = new byte[dataAvailable];
socket.Receive(data);

socket.Shutdown(SocketShutdown.Both);
socket.Close();

Receiving response(s) from N number of clients in reply to a broadcast request over UDP

help you fix your problem
How many times will I have to call recvfrom()? When will I come to know that I have handled the response from all the devices/servers?

/* get socket to receive responses */
sd = socket( ... );

do
{
    /* set receive timeout */
    timeout.tv_sec = 5;     

    /* broadcast request */
    sendto( ... );

    /* wait for responses (or timeout) */
    while(select(sd+1, &readfds, NULL, NULL, &timeout) > 0)
    {
        /* receive the response */
        recvfrom( ... );

        /* process the response (or queue for another thread / later processing) */
        ...

        /* reset receive timeout */
        timeout.tv_sec = 5; 
    }

    /* process any response queued for later (and not another thread) */

} while (necessary);

Why doesn't a HTTP reply from server specify the GET request to which the reply corresponds?

This might help you I needed to restart the server so the new methods could be pulled in. For the 1 person who actually reads this. To restart the server the command is pm2 start all
