Hatsune Miku, Megurine Luka, Kagamine Rin, Kagamine Len, Kamui Gakupo, Meiko, Kaito, Kasane Teto, Akita Neru, Yowane Haku, Sweet Ann, Leon, Prima, Lola, Yokune Ruko, FL-chan, Miriam, Big Al, Delay Lama, and Polar Bear Chaos
Neru, Haku, and Teto need no explanation. Leon (English), Lola (English & German), and Miriam (English) are 1st gen Vocaloids like Meiko and Kaito. Sweet Ann, Prima, and Big Al are all English 2nd gen Vocaloids. Ruko is just like Teto; she's another UTAUloid and fake "Crypton release" created by 2ch. Delay Lama is a simple voice synthesizer synced to a monk avatar who can only sing certain chanting sounds for mantra, but that certainly didn't stop people on Nico from making him sing complex songs. Polar Bear Chaos is a Vocaloid of some sort from a Japanese PS2 game called "Kuma Uta" (literally "Bear Song"); his voice sounds like an older Japanese male.

Wait.... Isn't that one that's supposed to be Leon called Leno? I believe the most popular fanmade character design for Leon is a young blond haired man, and that particular Leon design in the picture is called Leno. That's what I heard, anyway.
