It's hard to say for sure. Both Vegeta and Jiren are incredibly powerful, but it might depend on their current states and the circumstances of the battle.
In some fanfiction, Vegeta might see Trunks in a different timeline. For example, a timeline where Trunks has made different choices and developed a different personality. This can lead to Vegeta having to re - evaluate his understanding of his son and their relationship.
A good one might be where Vegeta sees Trunks' potential early on. The story could focus on Vegeta taking it upon himself to train Trunks more rigorously than in the original series. This could lead to some really cool battles and character development for both of them.
There probably is. Fanfiction is a vast world where all kinds of ideas are explored. Since Naruto and Jiren are from different anime universes, a fanfiction about Naruto being a fan of Jiren could be really interesting. It might involve Naruto somehow learning about Jiren's power and being in awe of it. Writers could play around with different scenarios like Naruto trying to train like Jiren or even seeking his advice in the fanfiction world.
One possible plot could be that Naruto, through some sort of interdimensional rift, witnesses Jiren's power during the Tournament of Power. He becomes so impressed that he starts to study Jiren's fighting style and tries to incorporate it into his own ninja techniques. This could lead to Naruto facing some resistance from his friends and teachers who don't understand his new fascination, but Naruto persists in his pursuit to become stronger like Jiren.

Yes, there are some. In some fanfictions, they might start as rivals but gradually develop a deep bond that could be interpreted as love. However, these are often very creative interpretations that deviate from the original animé's more straightforward rivalry theme.
One key element is the near - extinction of his race. This event had a profound impact on him and motivated his pursuit of strength. Another is his membership in the Pride Troopers, which shaped his fighting style and his sense of justice. Also, the destruction he witnessed in his youth is an important part of his back story.
