Don't use Titan Panel. Just use an actual DataBroker display addon. Yes, Titan "supports" DataBroker plugins, but it is still written on an ancient and bloated "closed" API, and is way less customizable than an actual DataBroker display (since there are dozens of them to choose from, and they're all configurable to some extent).
The raid frames in the upper right corner look like the old PerfectRaid addon, but you could achieve the same look with pretty much any custom unit frame addon.
The compact combat log thing next to the minimap is
EavesDrop or something like it.
The buff bars in the upper left could be Rave or ElkBuffBars.
