I could easily see Elise being rivals with Weiss or Neo(possibly a battle of graces?)

Marl vs. Jaune, a rivalry based on preliminary mediocrity (at least compared to their respective teams)

Aur vs. Blake, as their previous ties make them outcasts, Aur may point out, but Blake finds it hard to overlook the fact that he's human

Amphitrite vs. Neptune, probably as a friendly sort of rivalry due to their mythological name ties (yay! themes!)

Aaaaand Vienna vs. Ruby, with Vienna being upset that Ruby acts so chipper and comes naturally into hunting whereas she was only exposed to the dangers and risks of hunting
