The Legend
In ancient times, according to the legend, each elemental god was sealed into an elemental shrine. Out of the 9 Bijuu, 5 of them were elemental gods, those being Shukaku, of the Wind; Kyuubi, of Fire; Isonade, of Water; Raijuu, of Lightning, and Kaku of Earth.

There were respective shrines dedicated to these elemental Bijuu scattered throughout the world, being the Fire shrine the strongest. Though, the shines keep releasing spiritual energy even while the Bijuu are sealed within sleeping, and this power from the 5 shrines goes to the Five-Tails: Houkou.

After a mysterious yet powerful ninja got the legendary sword Hakaishi from the an ancient Ninja Clan, it defeated Nekomata and Houkou.

The mysterious ninja then proceeded to release a tremendous amount of dark power to awaken the five elemental Bijuu, that were sealed in the 5 shrines, with the purpose of bringing chaos between worlds.

It ended up fighting the one deserving of the title “King of Bijuu”: Kyuubi no Youko, which had Nine Tails and resembled the fire had an unending amount of chakra, and because of that, the mysterious yet powerful and evil Ninja was defeated, but, the Bijuu were all released still, Kyuubi no Youko was declared the King though, and still remains...

NOTE: Alot of these aren't actually confirmed by Masashi, in truth, only a few Biju have ever been actually shown in the manga and/or anime, some of them are just biased guesses from others, based upon Japanese Folklore or Chinese Folklore, so, please, some of these aren't canonically correct, for we don't actually know them. Thank you.

Eighth Tail: In this stage, like the previous, kyuubi has alredy takken control over the jinchuuriki. However, it's power's aren't yet at full, and the jinchuuriki may still return to normal, althoght that is something that only will happen after a long wile, or if the jinchuuriki dies. The Jinchuuriki appears as the Kyuubi's muscle tones, without any skin, but, its bones are forming, almost completely full.
Ninth Tail: The Kyuubi is released, destroying everything on it's path. In this stage, the jinchuuriki will probably be consumed by it thus being killed.

For The Jinchuuriki

All the Jinchuuriki's have some phisical caracteristic similar to his bijuu (like Naruto's wisker marks on the face, and Gaara's dark shades arround his eyes). Every time the they use the bijuu's power, it damages his/her body and unleashes a bit more the bijuu and the more tails the jinchuuriki would unleash the more this would happen (higher damage to the body and more freedom to the bijuu). Ultimately, the bijuu would be free and it's full power could destroy the jinchuuriki's village. Also, the jinchuuriki would be killed.
