They're all pretty much identical to current heroes... The nurgle guy looks like he's based off of the foremost blightking here, right down to the spikes on his pauldron. We only get a glimpse of the guy just above him fighting the fleetmaster but based on the naked back and the curved shield, looks like he may be a Kairic acolyte.

Ooh. There are two different size of the image, if anyone's poring over them, with slightly differing coverage. One in the article, one on the main WHC page. Looks like the Lord Castelant, Loremaster, Black Ark Fleetmaster and Cogsmith are down as heroes. They look to be fighting a blightking on the left but you can also see the head of a chaos sorceror lord's staff on the far right. Not sure who the guy just to right of the fleetmaster is... red armour and a two-handed axe might mean a slaughterpriest.

Gotta be honest though, Exoatl would be a far better name for former lizardmen than Seraphon.
