NO. Plus you spelt it wrong man.
I don't really know if there actually is any influenced Anime based off Vocaloid...Black Rock Shooter looks identical to Miku, but Black Rock Shooter was actually made before Miku...so there's actually no relation between Black Rock Shooter and Vocaloid.
Well I don't know about Black Rock Shooter but Vocaloid doesn't have any anime based on it. Although there are rumors floating around that they are making one.
Hatsune Miku sings the original Black Rock Shooter. Many other versions have been made.
Vocaloid was made to be a software that sings for you, and looks like a manga character. No, there isn't a anime, but there is Hatsune Mix, a vocaloid-based manga. Also, there's Black Rock Shooter, An anime being made based off of the song by vocaloid Hatsune Miku.

Piko is the name of both the Vocaloid and the voice provider, who is naturally not a Vocaloid.
No Teto is not a Vocaloid. I have heard before that She was made to be a prank. She is mistaken to be a Vocaloid. She sounds like a Vocaloid(y) software.
Kenmochi Hideki is the maker of vocaloid.

Well this question has been buzzing around now for quite a while so this is a good one. Kei the person who wrote the manga didn't intend for it to be an anime. Even though many people want it to be. It came out three years ago, so it might just need more time. even if there won't be an official anime people might still make it into a fanime. (A fan made anime) Check out: http://vocaloid.wikia.com/wiki/Vocaloid Actually, it is KIND OF Vocaloid, there's even a trailer. Have you heard Black Rock Shooter by Hatsune Miku? That's what they're going to make an anime of. Comes out sometime in 2010. Look for it! Black Rock Shooter (Pilot Version)
No, Vocaloid is not an anime. Vocaloid is a singing voice synthesizer software that allows users to create songs and vocals using virtual characters. However, Vocaloid characters have been featured in various anime and manga series.
Yes. Criticism is everywhere. You can find it on Youtube Videos, Vocaloid communities, ect.
