Could anyone tell me what's going on on this pic?
Thanks in advance...

ROFL awesome pic. I'm still a noob in Japanese, so please correct any mistakes.
(*) = May not be exact, but should be roughly
(**) = I have no clue...

Upper right: Of all the people having been hit by Nanoha, the scale of how close they became with her. (*)

Middle bar. RIGHT to LEFT:
Physical slap() (in grade 1). Alisa: "Even so, I was the first one." ()
Easy-strength cross fire. Teana: "E... easy-strength!?"
Divine Buster (counter). Vita: "Err, no thanks."
FULL STRENGTH SLB. Fate: "EH!!?"
Blaster-1 Excelion Buster. X: "Release me~~~"
Blaster-3 Excelion Buster. IV: "The... dream~~~"
Blaster-3(?) FULL STRENGTH SLBx5. Vivio: "Number oooooone"

Bottom.
Fate: "Nanoha, Shoot through(*) me right now!!" "With that pink (**)!!"
Nanoha: (Nyahahha) "What are you talking about, it's (**) Fate-chan~"

Sorry the box for IV should be "Blaster-3 Divine Buster", not Excelion

just thought I'd throw in some of my versions (I'm not gonna bother w/stuff I agree w/anonymous)
I'm doing this while (still) trying to get through ep.10 translations (of which I hope to get done very soon), so excuse my sloppiness
my personal notes are denoted w/italics

Upper right - Rule: the harder you get beaten by Nanoha-san, the more you get hooked on her. (*with some exceptions)

Middle scale, from right to left:
Body language taken to the extreme (in Gr. 1). Alisa: I'm telling you, I was the first one.
Cross-fire held back. Teana: "H-held back?"
Divine Buster (direct hit evaded). Vita: "Um, I don't mind, but..."

Bottom:
Fate: "Nanoha, pierce me through right now!! With that fat pink thing of yours!! (probably referring to Blaster-3 SLB)
Nanoha: (Nyahhahha) "...I have no idea what you're talking about, Fate-cha~n"

Is Rein pimping Vita?

Just commenting to say Azure has the more exact translations for those parts ^^
