Godzilla could be a new kind of threat that the characters have to deal with. Since Highschool DxD has a lot of supernatural elements already, Godzilla could be seen as an even greater supernatural force. It could be that a dark magic spell accidentally brought Godzilla into their world.
Godzilla could be integrated into the Highschool DxD storyline by being a misunderstood creature. The characters could start off seeing it as a mindless monster, but then they realize that Godzilla has its own motives and reasons for its actions. Maybe Godzilla is actually trying to protect something in the Highschool DxD world, like a powerful energy source that if misused could destroy both worlds. So, the characters from Highschool DxD have to work with Godzilla instead of against it.
In fanfiction, Godzilla might be a part of an ancient prophecy in the Highschool DxD world. The characters might initially not understand how Godzilla relates to their world, but as the story progresses, they find out that Godzilla has a role to play in either saving or destroying their world. For example, Godzilla's power could be the key to sealing away an even greater evil that is about to be unleashed in the Highschool DxD universe.
Well, he could be a transfer student. Just like any new character in the Highschool DxD world, Naruto could enter the school and immediately draw attention due to his strange powers and different appearance. His Juubi - influenced abilities would make him a target or an ally depending on who discovers him first.
Yes, there might be. There are a vast number of fanfictions out there for various combinations of popular culture elements. Since Highschool DxD has a large fan base and Godzilla is an iconic figure, it's not unlikely that some creative fans have combined the two in a fanfiction. You can try searching on popular fanfiction websites to find such works.
Naruto characters can fit in by being exchange students. For instance, Naruto, Sasuke, and Sakura could be sent to the Highschool DxD world to study their magic and combat techniques. They would bring their ninja skills and unique personalities. Naruto's never - give - up attitude would stand out among the devils and angels, and he might inspire some of the characters there to be more persistent in their goals.
Naruto characters can fit in by sharing their combat skills. For instance, Sasuke's Sharingan would be a powerful asset in the battles of Highschool DxD. It could give him an edge in detecting hidden enemies or predicting their moves. Also, Naruto's positive attitude towards his opponents could influence the way the more combative characters in Highschool DxD view their enemies.
One way Spiderman could fit in is if he was brought there by some sort of magical or scientific accident. He could then use his spider - sense to detect the hidden motives and powers of the characters in Highschool DxD. He might get involved in the power struggles between the devils, angels, and fallen angels, trying to maintain a balance. His suit could also be modified with some magic or technology from the Highschool DxD world to give him new abilities.
The OC, as the Son of Sparda, could fit in by being a new and powerful entity. He might be initially seen as an outsider, but his powers would quickly draw attention. He could become involved in the power struggles between the different factions in Highschool DxD. For example, the devils might try to recruit him, while the angels might be wary of his presence. His unique abilities would also make him a valuable ally or a fearsome opponent. And in the high school setting, he could be a bit of an enigma to the other students, both human and supernatural.
Kiryu could be a lost relic from an ancient civilization in the RWBY world. It has been dormant for ages until the RWBY characters accidentally awaken it. Since it has Godzilla's essence, it has incredible power that could tip the balance in the fight against the forces of evil in RWBY.
Naruto characters could fit in by bringing their unique abilities. For instance, Naruto's rasengan could be a new and powerful attack in the Highschool DxD world.

Well, the Bleach captains' abilities are quite powerful. For example, Hitsugaya's ice-based zanpakuto could be used in interesting ways in the DxD world. It could freeze demons in their tracks.

The OC gamer could fit in by bringing a fresh perspective. For example, he might introduce new technologies or ways of thinking based on his gaming experiences. With Raynare, he could start by trying to understand her motives. Maybe he offers her a deal where she helps him navigate the world in exchange for something she wants. This way, he can gradually build a relationship with her and find his place in the world.
