Though I've never met him personally, I have had people, mostly supervisors that I've wondered about. I'm told Lucifer is a pretty smarmy dude, coming off like he's super handsome, intelligent, and when he's not self-absorbed he's ingratiating with ulterior motives. In many ways, he's your garden variety boss.
And even with all of his flaws, you gotta admit, he's a bit of a bad-boy pop icon. He even has his own T.V. Series!
According to tradition, he's the 'fallen star' and the 'morning star' which is actually Venus.
Interestingly, there was almost as much on IMDb as there was on Wikipedia. That's how popular Lucifer has become since his biblical days.
