Answer 1

That's what the requestCode is for. So you'd have a setup like this

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
    super.onActivityResult(requestCode, resultCode, data);
    switch(requestCode)
        case ACTIVITY1:
           if(resultCode == RESULT_OK)
              Toast.makeText(getApplicationContext(), "Activity 1 returned OK", Toast.LENGTH_LONG).show();
           break;
        case ACTIVITY2:
           if(resultCode == RESULT_OK)
              Toast.makeText(getApplicationContext(), "Activity 2 returned OK", Toast.LENGTH_LONG).show();
           break;
}

Where ACTIVITY1 and ACTIVITY2 are constants in your Activity. You'd call them like so:

startActivityForResult(activity1Intent, ACTIVITY1);

and

startActivityForResult(activity2Intent, ACTIVITY2);
