There is no leader. Vocaloid has no canon, either. Everything about the fandom is made up by the fans.
Some consider Hatsune Miku the "leader" of the Vocaloids for her popularity, but this is just a private opinion.
No. VOCALOIDs are not couples. VOCALOIDs do not have to deal with anime or couples. It's only a singing program.
There are a lot of VOCALOIDs. VOCALOIDs are now up to at least 45, and their are more than 60 voicebanks.
Every VOCALOIDs have diffrent prices. The cheapest VOCALOID is currently $40 dollars and the highest price is about $400. You can buy the VOCALOIDs in their company's website.
Gackpoid does not have an official age and most VOCALOIDs don't.
You can get VOCALOIDs from their own companies: Zero-G ltd. Dear Stage PowerFX Crypton Future Media I-Style Project Bplats. Inc Internet Co. Ltd. AH-soft YAMAHA (you can even buy all VOCALOIDs from there, including their own VOCALOIDs) Ki/oon, or Sony Japan 1st Place (It's a company) SBS Artech Y2 Project VoctroLabs

To me i think Vocaloids did
depends on which one you buy. Luka is bilingual and can sing very well in english., and all the vocaloids can sing in english, but you can barley understand them.
Well, if your going in chronilogical order it goes: First generation vocaloids (MEIKO, KAITO, ...etc) Second generation vocaloids (Miku, Rin, Len, Luka...etc) Utauloids or UTAU's (Teto, Neru, ...etc)
