Under Saul, some army captains included Abner and Joab. Under David, some of the army captains were Joab, Abishai, and Benaiah.
David
To prevent Saul's army from needing to engage with the Philistines, David accepted the "contest of champions" against the Philistine champion, Goliath.

King Saul was jealous of David, but Saul offered his daughter, Michal to David as a wife. David said he was too poor to give a dowry to Saul for his daughter, but Saul said he wanted no dowry, but wanted David to avenge him (Saul) upon the Philistines by bringing 100 foreskins of the enemy back to him. But Saul's motive was not what he said, but rather he wanted David to engage in battle with the Philistines in hopes that David would be killed.
At first, David served as the leader of Saul's army, and also became a close friend of Saul's son Jonathan (1 Samuel ch.18), after he (David) had defeated Goliath (1 Samuel ch.17). Later, he became Saul's son-in-law, when he married Saul's daughter. See also:More about David
Saul reigned before David. Each of them had a standing army, and officers who governed (unlike the Judges). Each of them fought Israel's enemies. Each of them was guided by prophets.
There were too many Captains in the Confederate Army to list individually.
No. Saul's son Jonathon was killed along with Saul on Mount Gilboa when the army of Israel was defeated by the Philistines.Probably you are thinking of King David's son, Absalom, who had long hair which was caught in an oak tree as he was fleeing the army of David's general Joab. Joab then caught and killed him. Thus Joab was the one who killed him, although the tree played a part, as did his hair.
Abner
Jesse sent David with some provisions for the three oldest boys, who were in Saul's army. (1Samuel 17:13, 17, 18, 20)
For the army: General distribute the forces; Colonels control the battlefields; Captains fight the battles.
