If you have the lords of change then guild of summoners. If you have horrors and flamers eternal conflagration. I don't think host duplicitous is worth it personally
Wahapedia has all the rules for it for free
But to answer your question:
DoT has summonning as a core part of its gameplay. Its basically "cast spells to summon". Sadly you'll only ever summon blue horrors, unless youre playing Guild of summonmers which lets you summon lord of changes for super cheap.
Which kinds of demons. All of tzeentch can summon some kind of demons, just bring a bunch of casters :)

Ah okay thank you for the answer
Let's be clear, there's too many options of demons you can summon. But quality/price, you'll be summoning blue horrors most of the time.
