Forum:KB:Clone trooper designations

There's an article on the Star Wars website that is about the various clone commanders and captains throughout the Clone Wars. There is some canon information in there that is not in Legends (such as CT-7567, CC-5576-39, and CC-3636 being on Seelos), yet many of the troopers' names/designations weren't seen or heard in any canon media. (For example, Captains Zak and Silver were named in the article, yet they weren't named in the TV series.) Are these designations and/or names canon as well? Here's a link to the article: http://www.starwars.com/news/kaminos-finest-captains-and-commanders-of-the-clone-army
