Kiba and Sakura are just friends. They don't have any kind of romantic relationship among them and it doesn't seems that they will ever have one.
Pretty much everyone does but kiba likes hinata and in the end I think she gives up on naruto and goes to kiba either that or sakura gives up on sasuke and goes to kiba.
Nobody knows who Kiba will marry. Not sure how to post a new answer so I will add on to this it is unconfirmed whether Kiba has married however he does end up inviting Tamaki, the granddaughter of the old cat-lady Nekobaa who would supply the Uchiha clan with weapons, to live with him. Being a Japanese manga and the way the culture is it is highly unlikely they are not at least engaged if they are happily living together.
No.
no.
No
There are no Runo in Naruto
sakura from gakuen Alice ? she ends up with natsume if that's who you mean
Masashi Kishimoto has not said anything about Kiba and Hinita getting together later on. In fact Hinita has just told Naruto that she loves him so I am guessing that their relationship will be building. We'll see. If Naruto accepts her then Sakura and Sasuke are a sue in which mean's Kiba will end up with either Ino or Ten Ten.
Kiba may marry Hinata, but nobody will know for sure until Kiba actually marries.
Yes ! Yes ! Yes ! Yes ! Yes !
No she end up with shikamaru or kiba.
The manga hasn't finished yet but I still think that Sakura Mikan will end up with Hyuuga Natsume
