I’m personally terrible at this because I don’t know my celebrities very well, but I think we need to double-check if the judges are satirical characters of real persons. If so, names are available as puns.

I think we should really walk you through making good screenshots. Because taking pictures of a screen with a phone is not a good way of making screenshots.
Alternatively, you may go through the existing screencaps here on Derpibooru and crop out whichever pony you need a picture of.
Found 2 more unnamed background ponies from the movie. Another Bon Bon recolor but her color scheme is so pretty. And the light blue unicorn with pink hair. My name suggestion for both ponies: Rainbow Candy and Sweet Cream.
