Answer 1

Add an event listener to each child that will update a currentChild property by getting the name of the clicked element.

 var previousChild:DisplayObject;
 var currentChild:DisplayObject;

 panelChild.addEventListener(MouseEvent.CLICK , clickHandler );

private function clickHandler(event:MouseEvent):void
{ 
  //to avoid an error on the first click
  if(currentChild != null )
     previousChild = currentChild;

  // do whatever you need to do here, after it's complete, update the currentChild value;
  // this way the previousChild value indicates the object that was clicked before

  currentChild = this.getChildByName(event.currentTarget.name );
}
