Look at this picture of Hermione. Now look at this picture of Dumbledore. The picture of Hermione is an exact match, as the Dumbledore - down to the hat.
"Harry Potter" is incorrect for #3. I have no idea who he is.
Look closely at the tip of her wand - it is a bottle, one highly similar in shape to the Jeannie Bottle.
Plus Firiona's outfit looks nothing like the one the Erfworlder is wearing. It doesn't even have pants! Jeannie's on the other hand, is almost an exact match.
