You are correct; only one allegiance can be given to an army regardless of the units in it. The keyword abilities of the units themselves would still work though, such as the chaos lord's.

Thank you, I thought that was right. I'll have to give the army some good thought.

If you take a Disciples of Tzeentch army with marked slaves to darkness do they still get the re-roll of 1 to saves from the slaves to darkness allegiance? I'm thinking they don't as it would be a Disciples of Tzeentch allegiance instead but I thought I'd check. If not it seems Slaves to darkness tzeentch units are a little worse in disciple lists. 

I hope all this makes sense (I've confused myself a little writing it ?).
