Yes he is very strong, hence his chakra's are also strong. Not only this, since he is an uchiha, strong chakra's are common to him.
Since Sakura has great chakra control, Tsunade taught her to focus her chakra in her fist, foot, etc. when she attacks. She is not super strong with no muscles, she uses chakra.
He is not made of chakra. It is just that he emits chakra to control his 6 paths or bodies. The bodies then receive the chakra through chakra recievers.
Very unlikely.
It never says what Karin's chakra nature is.
I'm pretty sure exerted all his chakra, and he was already weak from chronic illnesses that eventually caught up to him. the only other thing i would think of is that him killing his family took its place in his heart and started to eat away at him, thus Itachi tried extending his life just enough to die by Sasuke's hand.

No
Sakura is good at controlling her chakra and becasuse of her medical training that required good control of chakra, she can use that skill to make her every attack stronger like Tsunade.
yes............she actually has some chakra of the nine tails.......hence she nowwhere near as strong as naruto
Really good!
Sharingan
He doesn't have one.
Suaskes (?) If you're talking about Naruto, Sasukes parents actually get killed by Itachi (Sasukes older brother)

If you think how strong chakra is without natural energy, it should make Naruto at least 1/3 stronger considering there's 3 types of chakra now.
