I'd like folks thoughts on this. This might also be a helpful thread to continue the discussion started here.
Here's my understanding of the titles:
1. The adventurers present at Carteneau who were sent forward in time by Louisoux are considered "Warriors of Light," per 2.0 starting MSQ (see: banquet scenes, Cid's special 2.0 dialogue for 1.x players).
2. Those adventurers and other individuals seen in 2.0's introduction to Hydaelyn after the MC acquires his/her first crystal are known and referred to as "Hydaelyn's Chosen" frequently throughout 2.x and 3.0. This seems to correspond so well to those who possess the Echo that the two seem almost interchangeable; if you are one of Hydaelyn's Chosen, you likely possess the Echo. In any case, that there are many of these individuals, and that not all of them are adventurers, is something confirmed both by Minfilia's existence and a 3.0 MSQ lore drop courtesy of Iceheart and others.
3. There is some ambiguity over whether the MC of 2x./3.0 is one of the Warriors of Light from 1.x or not. This is to accommodate the difference between 1.x players and 2.x-only players. In any event, the 2.x/3.0 MC is eventually acknowledged as a Warrior of Light, even if only as a new one. This makes it seem that "Warrior of Light" is more a title than anything.
4. The companions of the 2.x/3.0 WoL MC who aid him or her at various points throughout the MSQ - the assault on Castrum Meridianum and the Praetorium, for example - are acknowledged as highly-skilled fellow adventurers. It is heavily implied that these particular individuals are also Hydaelyn's Chosen. Whether or not they are Warriors of Light is up in the air. They are NOT, however, the Bringer of Light, which we're getting to right... now.
5. The title of "Bringer of Light" is specifically given to the 2.x/3.0 WoL MC, and canonically speaking there is only one such individual. This also aligns well with the 3.0 MSQ spoiler that...
EDIT: I've avoided touching the subject of "Hydaelyn's Blessing" because I'm not sure whether it's ever definitively stated exactly WHAT that refers to: whether it's the Echo, or the Bringer of Light's enormous capabilities that Midgardsormr seals away, or just Hydaelyn going "YO, DAWG, YOU'RE MY HOMIE." See Sounsyy's post here for more.
