You confirmed Lego got 3 right and Zak 1. Rick gave away he was 4, thus ninja couldn't be 6. The only other girl is djodessa so she is 6.
The only other difference between zak and Lego was the placement of Antoine and Florian, thus Florian was 2, Antoine 3.
Ninja is a graphics designer I believe? 5 is more interesting to look at! That left Vlad as 1.
Mickey was just that you wouldn't show the ears as it would be too easy therefore you had to show the legs, once you know you are looking for skinny legs its a lot easier!
