DEldar will never ally with Chaos, they fear Slannesh too much.
I don't know that it's so much that the DE fear Slaanesh, but that they're too involved in their own insane and inane self-pleasuring acts to see anyone else worthy of an alliance. The Emperor's Children who follow Slaanesh would be the only candidate for an alliance, seeing that the DE have a common ground with them. Outside of that, there is no hope. The other armies would be better off shooting themselves than fight the DE, for everyone knows it's better to die in battle than be taken as a slave for the DE. Who knows what horror awaits them and what has been done in Commoragh to please Slaanesh.
Orkz don't usually ally with Chaos either. Rare occasions, but they're mostly because the Warboss that decided to ally with Chaos (or any faction for that matter) is for his WAAAGH!'s own gain. This is usually in the form of guns, armor, or territory (gubbinz, choppaz/shootaz, an' more WAAAGH! room) The main reason Orkz don't ally with Chaos is because they aren't susceptible to mind control. All Orkz have some basic psychic power, to what end isn't exactly known. What is known is that this slight ability allows each and every Ork to know who is 'Boss without being directly told. This ability also allows Orks to be used as a psychic weapon. Ork Shamans feed off of this power. Gather a large enough mob, put a Shaman at its center, and grab the sunglasses. Things could get messy in a hurry, and it doesn't always go in the Shaman's favour either (I lose more Shamans that way...)
The Empire of man may or may not ally with the Tau. Hails from Tau ships and planets are automatically censored before they reach the Empire's soldier's ears. Typically Tau messages offer potential invading armies an opportunity to fight for the Greater Good as a means to try and gain more for the cause. The messages are censored because the Imperium believes its masses minds are too weak and fickle, and therefore might try to join the Tau. Only in dire situations might the Empire join with the Tau, but it'll be a "you don't shoot me, we won't shoot you" circumstance. Then the "treaty" might be broken once the objective is reached.
The Eldar might be the only race that would actually ally with the Tau, but again, it's not certain. The Eldar are the wisest race in the entire universe and they've suffered greatly. They've made the necessary adjustments to prevent another Great Fall, but this does not always mean they'll ally with another race.
To my knowledge, the Necron never ally with anyone. A Necron Warrior doesn't even have the luxury of free thought or speech. All Necron Lords are cursed with this luxury and the memory of how the C'Tan tricked the frail Necrotyr many eons ago.
Chaos Renegades are those minds weak enough to give in to the whispers of Chaos. Renegades can happen to any race, including Orkz, but it more rare than any race.
