Based on this passage, I believe that the description which best characterizes Hector is the last option - he is an epic hero because he is a brave leader. You can see in the excerpt that once he started walking around his men, they all stopped talking and calmed down, as if they admired him a lot, which was the truth. He was a good leader and his men loved him, and were devastated when he was killed in the end.
He is an epic hero because he is a brave leader. I would say that this is the most likely description of Hector because he had the courage to go amongst the Trojans and quell their unrest by a motion with his spear and get their attention.
