These are the names I have found. Note, a few of these share the same name but not the same Lore of the Halo 5 Armors (Breaker and Void Dancer for example.) and others share a 3d model that is the same as a Halo 4 and 5 model (Stealth being Venator). For those that have a name that is the same as another armor design from Halo 4, 5, and 2 Anniversary, I have made a new name to better distinguish them. That and also to avoid some possible copyright such as Goku and Optimus being renamed.
I compiled these from both Halo Online and Halopedia, but also a guy who made a list of models that he datamined from Halo Online, and posted on a cosplay design website :

Now if only 343 included these into Halo 5 when Halo Online was cancelled, since they work the same engine and near-identical art style.
