I can't really say for sure who I have the most, but these characters are those I have a ton of respect for.
Hinata: Unlike every other character on this list, Hinata isn't a Kage level shinobi, and yet here she goes with the same courage to fight their common enemies. Stood up to Pain like Jiraiya. Was ready to be impaled like Naruto's parents (was impaled if you think back to Pain). Now she stands almost at the head of the Shinobi world against the Juubi. Also, she may not have natural talent, but she works hard and shares the motto of the one she loves. (Figures I'd explain more for her since she might seem like an odd choice)
Kisame: I believe the only character to commit suicide in order to protect the endeavors of comrades. Probably the only heroic death in a situation in which he really DIDN'T HAVE to die...just imprisonment.
Itachi: Though other alternatives should have been made, he killed his clan to save his brother and his village.
Jiraiya: died trying to find the Key to Pain
Minato: died to save his son and village
Then I'd give attitude/appearance props to:
Kakuzu: didn't underestimate foes (a rarity in antagonists it seems)
Shikamaru: strategy and demeanor
Han: Kasa, Armor, Jinjuriki, FALCON KICK
Kushina: died to save her son and village
Rock Lee: Went into shinobi life already screwed cause he lacks Jutsu skill....has become an amazing shinobi.
Neji: Died protecting his cousin and Naruto
