Depends on the story generally people say no however on very rare occasions there are days demons who are "good":

Sparda(Devil May Cry) - Turns on the other demons to save humanity.

Dante and Nero (Devil May Cry) - If you count hybrids or partial Demons as they fight to protect the world.

Etrigan (DC) - Fights the forces of evil though I think it might be the host.

Hellboy (Dark Horse) - Rsised by humans and fights to protect it from demons and other evils.

Spawn (Spawn) - Fights to protect humanity from all threats including God (note he isn't the true supreme being but Satan's twin in this series).

Kurama (Naruto) - He and I think the other tailed beasts redeem themselves near the end of Part II.

There are probably some more but these are the examples off the top of my head on "Good" demons. There are also neutral (Not as rare) and evil demons.
