I don't work with Djinn in any real way but I've studied them a bit. From what I've gathered they seem to be more akin to Elementals then demons since Elementals also have "lives" and families and eat and sleep and stuff.Djinn and demons are 2 different things.
They totally feel different, use different ways to communicate and live in different places.
Generally speaking djinn live in a different dimension on earth, while demons live in the spiritworld.
Djinn have a lot in common with humans. Like family life, war, religion, oppression, etc. (probably more, but at the point of conversation i was at war myself so thats the info i needed)
Sadly there are and were also wars between djinn and humans. Due to that past some have a huge hatred against humanity, but there are also groups of djinn who feel like that, but in all actuality just radiate different. So it can be confusing, but that seems to be the whole point.
