[warhammer 40k] The Four Chaos Gods Nurgle, Khorne, Tzeentch and Slaanesh are all born from the negative emotions, bad deeds and war from sentient beings throughout the galaxy. Are there any gods of order born from positive emotions, good deeds and peace?

Another question, do other galaxies have their own chaos gods?

Chaos gods don't embody negative emotions alone.

Khorne for example is a god of blood, war and murder, but he is also the god of martial pride, honor and those who stand up against all odds and win.

Tzeentch is the god of change, evolution, intrigue and sorcery, but he is also the god of knowledge and comprehension.

Slaanesh is the god of pleasure, passion and decadence. He/She is the god of excesses as well. 

Nurgle is the god of disease, decay and destruction, but also the god of rebirth.

Basically, the Chaos Gods all have a positive dimension to them. There are many ways to the corruption of Chaos.
