Naruto is 8. Sora is 10. By the age of 12 Naruto had failed his graduation exam twice already. A normal student goes through the academy in 4 years. If Naruto failed twice than it most likely means he either enrolled at 6 and graduated in his 6th year or he tried to graduate early. Considering that the academy didn't kick him out after his first failed graduation exam I'm assuming they don't really care how old someone is as long as they have the means of becoming a ninja. Boruto has a kid who looks to be two or three years older from the children in his class as well. The Uchiha massacre is 4 years before the start of Naruto so my timeline may be off by a bit,, but the MC has also made some changes and confronted Itatchi. These are my ideas on the matter. If you have any other questions please let me know.

He is 2 years older, but there isn't a certain age that kids have to start the academy. There's a cut off age, but no age for starting. Sora is in the same class because he decided to wait for Narutos group.

So kushina has lost access to her Chakra. Normally when a Jinchuriki loses their tailed beast their Chakra will leave their bodies like a cup of water with a hole in the bottom. Minato sealed her Chakra so that it wouldn't leak out, but if she uses it then she will come closer to death. Minato tried to keep tobi from entering the birth site with his extensive seal knowledge, but its hard to keep someone out when they can travel between dimensions. MC asked Minato to act like he lost his shinobi abilities so that danzo wouldn't act against them yet. The MC wants the timeline to follow as closely to Canon as possible because the further it strays the harder its going to be to anticipate the enemies plans.

Not sure yet. So far I'm thinking maybe Ino, Temai, Mei-Terumi, shion, or shizuka.
