40k Dark Angels for use in 30k

Howdy folks! My father is getting back into the hobby and has taken an interest to the Heresy Dark Angels! We have a decent sized force from 40k, and I was wondering if any of these models had rules or a rough equivalent in Heresy. The units are: Deathwing Knights Deathwing Terminators Revenging Darkshroud Nephilim Jetfighter

This is all for mainly home play, just trying to see how/if we can use models we already own. Hope ya'll are having a pleasant day :)
