The first one is of the man in red suspenders. Wait for him to walk to the post box,and take a photo of him dropping a letter in it. Second is of a man in the cafe/bar. Throw a pot at him to make him scared, then take a photo of his scared face. For the last one, wait for the guy who likes to walk the town to walk by the lady in yellow. Take the photo when they look at each other as he passes
