Yes. when hinata is attacked by pein, naruto thinks she is dead and goes up to 6 tails in an instant. naruto keeps going to 9 tails, when he finds himself outside the gates of the kyuubi, and The 4th hokage appears, revealing to naruto that he had set it up so he appeared if naruto ever reached nine tails. he tells naruto he is his father.
naruto goes 6 tails in episode 167
the naruto has ever made it is to 8 tails and that was by accident he made 9 tails but the 4th sealed it and reveled that naruto is his son so naruto was the 9 tails for a split second when pein sealed him in a rock sphere thing.
Naruto goes 6 tails when he is versing Pain in the manga, book 47.
No.
after he turns into 6 tails

No. Well, not yet, atleast. Naruto does however, use ALL nine tails, when he fights Pain (around chapters 438-443). He starts with 6 tails, then Nagato stops him, and then Naruto uses all nine, but the 4th Hokage entered Naruto's conscience just before Naruto was about to remove the seal, and stops him.
Yes.
