She would likely be devastated. Kushina has a deep connection to Naruto as his mother. She might first go into denial, unable to accept that her son is gone. Then, she would probably be filled with intense grief and anger. She could potentially lash out at those she blames for his death or just break down completely, mourning all the things Naruto could have been and all the time they missed when he was growing up.
The village of Konoha would be in mourning. Naruto was a hero to them. Kushina's grief could spread throughout the village, dampening the spirits of everyone. There might be a sense of hopelessness as Naruto was often seen as the one to bring hope in difficult times.
She might be overjoyed. After all, Naruto is her son. She could immediately rush to find him and embrace him tightly, tears of happiness streaming down her face.
Jiraiya might comfort Naruto by sharing his own experiences. He could tell Naruto about the times he faced difficulties and how he overcame them. For example, he might talk about his training with the toads and how he grew stronger through perseverance.

In fanfiction, Jiraiya seeing Naruto as Hokage can be a very emotional moment.

This often shows Jiraiya's pride in Naruto and his belief in Naruto's potential to lead the village.
Naruto might initially be confused. He has grown up with a certain view of himself, and this new information about his heritage completely shatters that. He may struggle with his identity for a while, but as he digests the information, he could start to feel a sense of pride. He might think that now he has a greater purpose, something that ties him more closely to his family and the ninja world in general. He may also become more confident in his abilities, knowing that he comes from a great lineage.
It might be that the truth is about his own origin and the prophecy associated with him. He could discover that the village had been manipulating him all along based on this prophecy. For example, they might have been using him as a weapon without his full knowledge, and once he finds out, he decides to leave to find his own path away from their control.
