            if(relatedStories[j].yahki_thumb){
                var one = j+1;
                var block = related_stories.getChildByName('related_stories_block'+one);
                // load the image
                loadImage({
                    path:relatedStories[j].yahki_thumb,
                    success:function(e:Event,my_loader:Loader)
                    {
                        my_loader.width = this[block].width;
                        my_loader.height = this[block].height;
                        this[block].img.addChild(my_loader);
                    },
                    error:function(e:Event)
                    {

                        echo('error to load an image');
                    }
                });
            }
        }
        // replay button event

        // error
        echo('no related stories');
    }

Try this within loop:

   var that:* = this;
   (function(block:*):void{
       loadImage({
                path:relatedStories[j].yahki_thumb,
                success:function(e:Event,my_loader:Loader)
                {
                    my_loader.width = that[block].width;
                    my_loader.height = that[block].height;
                    that[block].img.addChild(my_loader);
                },
                error:function(e:Event)
                {
                    // error
                    echo('error to load an image');
                }
            });
   })(block);

As loading is asyncronous, when your success function is called, block value has already related_stories.getChildByName('related_stories_block'+relatedStories.length) value. That is the reason,elements were added to last MovieClip.
