Generations...

[recimo]

Who is same generation with who?

Naruto, Sasuke, Choji, Ino, Shikamaru... are same generation.
Kakashi, Guy, Kurenai... etc.
Itachi is same generation with Kakashi, Obito...?
Minato and Kushina are same generation with Shikaku, Inoichi?

 

[Uchiha Josephus]

Itachi is between Kakashi/Obito/Guy and Naruto/Sasuke (remember that he met Obito in the woods before he took out the Uchiha - you can tell the age difference)

Other than that, seems legit.

 

[recimo]

Oh yea. I remember.

 

[Prime Rib]

itachi was 13-14 years old when he left the leaf. kakashi is like 8-10 years older than him

 

[ShinraRengan]

Itachi would be in Temari's age group

yes

Itachi is same generation with Kakashi, Obito...?

No Itachi is younger, remember Kuybi incident, he was very young there, taking care of baby Sasuke. Itachi's generation is rather unknown. It's possible, that Yamato could be from his, and perhaps some of the younger looking Jonin's, who aren't team leaders yet.

Minato and Kushina are same generation with Shikaku, Inoichi?

Correct. Don't forget Choza
