In the first place it can't work because npc doesn't have original canvas size, is blurry and have one frame (animation frames are added vertialy bellow, it is same for every animated sprites), ... by that I mean that it isn't animated.
Other what I saw is that every sprite have white background, you should remove that too. Using original microsoft paint will now help you.
Other thing why they don't work might be because letters aren't in capital.
Sorry but other don't have time or propably mood to fix it for you.
