int num = (int) System.currentTimeMillis();

PendingIntent resultPendingIntent=PendingIntent.getActivity(this,num,resultIntent,Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);

mNotificationManager.notify(num, mNotifyBuilder.build());*

1) PendingIntent pendingIntent = PendingIntent.getActivity(this, 1, i, 0); 
  ..............Your code ........................  
    nm.notify(1, noti); 
2)PendingIntent pendingIntent2 = PendingIntent.getActivity(this, 2, i, 0);

3)PendingIntent pendingIntent3 = PendingIntent.getActivity(this, 3, i, 0);  
  ..............Your code ........................  
    nm3.notify(3, noti);
