The berserk has been mostly identified as Truan of the Hundred Battles (from "The Five Champions"--his flavor text suggests very strongly he was the one who got the head).
The Avatara in the tent are harder to pin down. One is definitely Alric. One, I theorize, is Rabican--he looks like a warrior with his helmet off, and Rabican is the only avatara known to wear extensive armor. The third person is without a doubt a Journeyman. He's wearing golden tiles and a necklace of stones and fangs. From this I have theorized that one of the Nine was not an avatara but a very old, very wise Journeyman.
There is also a figure standing outside the tent, holding what looks like a wizard's staff (it isn't a spear--the head is wrong). I've argued that this is Maeldun, based on the pregame pics from Myth II, which show Maeldun holding a similar staff, but this is shaky evidence at best.
