who are these guys?

okay i really need some help. for some reason...im stumped. and i feel totally retarded about it ive lately been going through all my wonderful jrock pictures and re-naming them and organizing them all in cute folders and such (ok, i can't make "cute" looking folders on my comp but hey...they contain cute guys so i'm calling them cute) i'm so bad about initially naming pics when i save them. i always just save it with the name it has or quickly run my fingers on some keys and click save. just so i have the pic. so now im left with a few pics of people and i have no idea who they are. PLEASE help me!
okay first off...i know this guy is from penecillin... but what be his name?



and then i just need to know who the following people are and what band they're from...please




EDIT: Shoot! i forgot one! who's this too!?

The first is Hakuei. The second is Jui from Vidoll, and the third.. looks like an old picture of Hiroto from alicenine?

yeah i was told it was hiroto when i got it but then i kept looking at it and it just made me wonder if it was really him

AH! Vidoll! geez i can't beleive i forgot that already! thanks muchly for informing me bout all of them!

The last one says its Tsunehito...so its probably Tsunehito from D But please correct me If I'm wrong

haha omg im such a dork. i meant to ask what band they were from. i forgot i already had the name. i seriously hate when i get something then forget who it is. i feel like such a fan failure

Haha I just know the first one is Hakuei from Penicillin. (at least in that pic it's Penicillin. He's also in Machine.)

muchas gracias para [the confirmation] Precious4e!
