I can tell you mine, but other than these you're on your own
My Grey Seer is named Grundz, because, being the general, he's my incarnation on the table.
My Chieftan is Daskit Ironklaw (named after my pet rat, who is named in true skaven style
)
My Master Moulder is Skreek Nikket (Skreek being the sound he makes when he spots a new monster, and Nikket being what he does to any beast he has a fair chance of capturing
)
My Assassin is Ikari the Swift (Ikari being from "Shinji Ikari" from neon genesis Evangelion")
And last, but not least, is My Warlock Engineer, named Quee Fiksit. AKA, Bob the Builder of wacky contraptions.
Hope that helped
(Otherwise you could just look in the Army Book
)
