Yes, he releases it until the 8 tails, then the 4th hokage (his father) takes him away and talks. He releases it when after Hinata was almost dead after Pain had stabbed her.
It goes in this order:
4th tail appears when Hinata is stabbed and Naruto assumes she's dead
6th tail appears after Pain asks if he hates him and Pain talks about war
8th tail appears when Pain uses the jutsu that a cannot spell but it is a black ball of i assume magnet chakra that collects earth and matter and traps whatever that is in the area.
He does, but I'm not gonna tell you the chapter ;)
Yes he does. While fighting the sixth Pain, Naruto is about to release the ninth tail in his demon fox formation. He is locked inside his own mind, and the Fourth Hokage appears to him, but he does not reveal that he is his father he just stands their holding Naruto's shoulder and smiling and naruto sees that its the 4th hokage.
it will release after you finish the battle
Gaara had the one tail in Naruto.
