For the kanji next to each character's names:

Kakashi: Endure Shikamaru: Will Hinata: Love Sasuke: Path Sai: Bond Sakura: Fate (Could be 'life' - Kanji often have more than one meaning.)

I'm sticking with 'fate' as it fits with the meaning of other characters' kanji better. Life and fate are, somewhat, related if you think about it.
