Warhammer 40k Thousand sons?

I'm a complete and total noob when it comes to warhammer 40k I just started playing and I bought a hodgepodge of an army (mostly thousand sons but also abaddon and some plague marines) My question is how do HQ units work? Right now since my friends and I don't know any better I've been using abaddon... show more I'm a complete and total noob when it comes to warhammer 40k I just started playing and I bought a hodgepodge of an army (mostly thousand sons but also abaddon and some plague marines)

My question is how do HQ units work? Right now since my friends and I don't know any better I've been using abaddon and Arihman but I don't think that's right? Can you field abaddon and arihman in the same army? And more importantly would you want to?
