So from left to right we have
Ulquiorra (Rank: Unknown. Is fairly cold and indifferent to most and one of Aizen's most loyal Espada responsible for kidnapping Orihimie and psychogically trying to break her)
Lazy Bones (Nickname due to not being named yet. Rank: Unknown. All we know is the guy likes his sleep.)
Nnoitra (Formerly known as Spoonhead. Rank: Unknown. Is tall and has a creepy smile made even more creepy by the fact he sounds like Dean Venture hitting puberty).
Mrs. Underboob/Censorboob (Nickname due to not being named yet. Rank: Unknown. The only female Espada who got her nickname due to her arrancar uniform, which as you can see was censored when it hit the anime).
Aaroniero Arruruerie(Rank: 9th. Former Nickname: Mr. Bubbles. For some reason talks with two voices and dislikes the light. And for some really weird reason looks like Ruika's old Soul Reaper pal and former vice captain of Squad 13, Kaien Shiba. What's that about? Find out)
Yammy (Rank: 10th. The first Espada we've met and from what we've seen essistanly dumb and fairly easy to beat. If you're not Orihime or Chad that is).
Old Guy (Nickname Due To Not Being Named Yet. Rank: Unknown. Nothing really know about him besides the fact he's... old.).
Syazel Aporro(Rank: Unknown. Former Nickname: NERDDDDDDDDDDDDDDDDDDDD. Syzael is apparently the scientist of Hueco Mundo and enjoys collecting new expierments to work on, even those of his fallen team-mates)
Affirmative Action Arrancar (Nickname Due To Not Being Named Yet. Rank: Unknown. He's Affirmative action because he's the only true black arrancar/Espada in the anime. Yammy's more mexcian, Underboob's a mulatto and Tosen isn't an arrancar).
Grimmjow Jagerjaquez (Rank: 6th. Ichigo's Espada rival who recently reclaimed his spot after taking out the replacement 6th Espada Luppi. His rage and rebelling attiduing also makes him one of the more popular Espada, especially around here).
