Add a parameter to your DownloaderAsyncTasks constructor. Use it at onPostExecute

int mIndex;
public DownloaderAsyncTask(Context context, int index) {
    mContext = context;
    mIndex = index;
}

protected void onProgressUpdate(Integer... progress) {
    Intent intA = new Intent("...");
    intA.putExtra("resultCounter", mIndex );
    intA.putExtra("int", progress[0]);
    context.sendBroadcast(intA);
}

protected void onPostExecute(ByteArrayBuffer result) {
    Intent intB = new Intent("....");
    intB.putExtra("resultCounter", mIndex );
    intB.putExtra("image", result.toByteArray());
    context.sendBroadcast(intB);
}

Change initialization of asynctasks with your new constructor.

for(int i = 0; i < 5; i++) {
    DownloaderAsyncTask asyncTask = new DownloaderAsyncTask(getApplicationContext(), i);
    asyncTask.execute(links[i]);
}

Also change the to resultCounter tag when you get progCounter value

// Broadcast receiver for PROGRESS BAR
BroadcastReceiver receiveProgress = new BroadcastReceiver(){
public void onReceive(android.content.Context context, Intent intent) {
   int progress    = intent.getIntExtra("int", 0);
   int progCounter = intent.getIntExtra("resultCounter", 0);
}

This is your mistake

In your BroadcastReceiver receiveImage

You are trying to get the value of progCounter from the intent. 

  int progCounter = intent.getIntExtra("resultCounter", 0);

But in your Async Task you are not sending any intent of resultCounter so each time you trying to get the value of intent it will give you 0 ("resultCounter", 0) as no intent is there.
