Brom, Eragon, Saphira, Arya and the Ra'zac are a few of them.
Five integral characters in Eragon are Eragon, Saphira, Brom, Murtagh, and Arya. Eragon and Saphira are doubtlessly the most important characters out of them.
Characters: Eragon, Roran (Eragon's cousin), Arya (elf who got the egg to Eragon) Saphira (Eragon's dragon) Brom (storyteller/dragon rider/Eragon's dad), and galbatorix (main antagonist).
The five main characters in the "Eragon" series are Eragon (the protagonist), Saphira (his dragon), Brom (his mentor), Murtagh (his ally and friend), and Arya (an elf princess). Their relationships and interactions drive much of the plot in the series.

While Eragon does draw certain elements from the Fantasy genre as a whole, the similarities between Eragon and The Wheel of Time are no more prominent than comparisons from any other Fantasy series.
I would say the random soldiers or housefolk who are included in the wars and battles.
