Hector was a prominent hero and warrior on the Trojan side during the Trojan War. He was the eldest son of King Priam and Queen Hecuba, and he was considered the greatest Trojan warrior.

Agamemnon was on the Greek side during the Trojan War. He was the king of Mycenae and the leader of the Greek forces besieging the city of Troy.

Agamemnon - king of Thebes - was commander in chief of the Greek forces. Troy's commander in chief was King Priam, but the army was under the control of his son Hector. What precisely happened to the Trojan command structure after Hector was killed by Achilles is not entirely clear from the stories we have, but Aeneas was in command of the city defenses, and probably took an even more senior role after the death of his commander.
Hector sided with his country, Troy, but he did not want the war to take place. He felt that Paris, his brother, was foolish to steal Helen away from Menelaus and risk his country and countrymen in a meaningless war with Greece.
It was pretty much the end of the war for the Trojans because it was believed that without a hero, like Achilles or Hector, that the war could not be won. Basically they believed that if the other side had a hero and you didn't that you wouldn't win.
