If Kakashi time - travels to the Kannabi Bridge, his relationship with Obito would be very different. Instead of the tragic end they had in the original timeline, Kakashi might be able to save Obito. This would lead to a much closer bond between them, and they could become a powerful duo in the ninja world. They might also be able to change the future of the Uchiha clan together.
His relationship with Rin would also change. With Obito alive, the love triangle situation could develop in a completely new direction. Maybe Rin would develop feelings for both of them, or Kakashi would step back to let Obito have a chance with Rin. And his relationship with Minato - sensei would be different too. Minato would be impressed by Kakashi's knowledge from the future and might start training him in new ways.
Kakashi's relationships with the enemies he faced during the Kannabi Bridge mission would also be different. If he changes the outcome of the mission, some of those enemies might not become his enemies at all. For example, if he prevents certain events from happening, some ninja from the opposing side might end up becoming his allies. This would completely shift the power dynamics in the ninja world and his place within it.
