Ask John: Who Do You Know?

Question:
many characters that i cant recognize and its bugging me
notable ones:

-the guy across hell teacher Nube, wearing school uniform
– the two guys to the left of Kankichi Ryotsu , one wearing school uniform and the other white cloth.
-the guy right to captain tsubasa, holding cards.
-the guy above sena wearing green suit, i swear i know but cant put my finger on it.
– the guy right under gentoki , with angry look
– and finally the guy steering the ship

Answer:
This is quite a challenge, and honestly I’m not the most expert at addressing it because my knowledge of Japanese animation is much more thorough than my knowledge of Japanese manga. Furthermore, the limited resolution of the image makes seeing small details difficult. However, I do recognize many of these Shonen Jump stars. The katana-weilding young man facing Meisuke “Nube” Nueno is Otoko Juku’s Momotaro Tsurugi. The young man in green at the top of the image, to the left of the tiny white horse Makibao, is Hunter x Hunter’s Gon while the man with a .357 and green trenchcoat beneath him is the City Hunter Ryo Saeba. Unfortunately, due to the image resolution, I can’t clearly see exactly who’s beneath Gintoki, but Takeshi of Seikimatsu Leader Den Takeshi is one of the characters immediately beneath Gintoki and to the left of Jotaro’s head.

If I’m not mistaken, based on the characters I can clearly make out, I can place or precisely name 26 of the characters in this image.
