I believe the Five Elders will be strong but not Top Tier level. Perhaps it is too soon to know already who they are going to fight, regardless, here is my attempt:
I think the sword guy (probably Mars) will turn out to be Imu's personal bodyguard, like Trebol was Sugar's. Trebol fought with Doffy against Law and Luffy. Mars will fight with Imu against Luffy and Dragon. The other four though will be defeated by women:
Jupiter vs Nami
Jupiter is known in greek mythology as Zeus. Just like Nami's cloud. He is said to rule of the sky. Nami has weather powers.
Saturn vs Bonney
Saturn is the god of time. Bonney has a DF that allows her to manipulate time. She has a big grudge against the World Government. She should be involved in the final battle
Venus vs Hancock
Venus is the god of lust. Hancock is the woman most lusted after. She hates the Celestial Dragons, was their slave once.
Mercury vs Robin
Mercury, also known as Hermes, is commonly depicted with winged shoes. Robin can also create wings.
