What do you know about the three guards around Naruto Namikaze Minato?

Shiranui Genma konoha was particularly tolerant and served as the examiner in the third round of the long-term exam?

He is similar to Tejen Konoha, and he is one of the few assassins.

Yamashiro Aoba Konoha Ninja Village is very tolerant and good at reading other people's memories and summoning crows?
