My two cent:

Grand Saber: Ali ibn Abi Talib wielding the two prong sword Zulfiqar.

Grand Lancer: Guan Yu and his Green Dragon Crescent Blade

Grand Archer: Many candidates, such as Archer Rama, Archer Karna, and Archer Heracles.

Grand Caster: Besides our own good doctor and Mr. Always-his-fault Merlin, we could also have Grand Caster Aleister Crowley.

Grand Rider: A rider known for his steed would be Noah and his Ark. A rider known for his riding skills could be Genghis Khan.

Grand Berserker: Lucifer the Adversary.

Grand Saver: Yeshua of Nazareth
