No. There are no tribes in Naruto. There are tailed beasts. (naruto being the nine-tailed fox host) And there are villages.
Kurama
Sora does not have a beast, just a portion of the Nine Tailed Demon Fox's chakra which Naruto Uzumaki absorbed back into himself.
Jinchuuriki.
The Third Super-Beast!
Yes when he needed to rescue Sakura from the sand and Gaara was on his tailed beast Naruto used the summoning jutsu and turned his toad into a fox representing the kyubi so that he could use the claws to get a grip on Gaara's tailed beast and then Naruto ran through the sand beast to head butt Gaara out of his transe. Naruto:1 Gaara:0
Probably not.
The last jinchuriki was Yagura who was able to have full control over the beast.

Naruto's Mum - Kushina Uzumaki - Was the precious Jinchuuriki (holder) of the Kyuubi (Nine-tailed-Fox) So I don't exactly know how she died. But because I know other accounts of tailed beast Holders dying I'm going to guess that When Madara Uchiha Used the Nine-Tails to Destroy Konoha, like how the Akatsuki Extracted the Tailed beasts from the Jinchuuriki's. He must of killed her In the process of controlling the beast. Or Maybe As Naruto turns into the beast from time-to-time Maybe Using the Mangekyo Sharigan, he used a genjutsu to control her as the beast and Naruto's Dad - Minato Namikaze - Fourth Hokage Sealed her in Naruto with the beast and himself.
Naruto transformed into the Kyubi when Jaraiya undid the seal, a little, to try and help Naruto get control over the beast.
there are 9 tailed beasts (demons) . but they have been taken by the akatsuki. naruto is the nine tailed beast.
Naruto and Naruto Shippuden...same theme it's about Ninja's and tribes (villages).
