After 4 years living in Japan and a few more of being friends with Japanese people, I've never encountered this name before. (doesn't mean it doesn't exist, but I've never heard it as a name)
"Ran" is also used as a pet form of the Bulgarian masculine name "Rangel". "Rangel" comes from the Bulgarian word 'angel', which means "angel" in English. "Rangel" is pronounced like 'angel' and the Bulgarian masculine name "Angel", which are pronounced [angel], where "a" is pronounced [a], not [ei], "g" is pronounced [g], not [dj] or [j], "e" is pronounced [e] and the stress is on the "a".
Ran is a character in the Japanese light novel Suki na Mono wa Suki Dakara Shôganai!' a.k.a. 'Sukisho!' (it has also been made into an anime, several games, etc.) Just as Yoru is the alter ego of Sora, Ran is the alter ego of Sunao. He is much more feminine than his counterpart. He is dependent and demanding, and deeply in love with Yoru.
