Hard to pinpoint only 5, but one that definitely always stands out for me, is the South Gate scene.
I don't know if it is the music, the dialogue ( "Really? I don't like wars. Why would someone start a war..?" / I'm telling you, people who eat pickles are nice people." ) the excitement I always have when I am that early in the game when I replay it, it's probably a combination of all, but I just adore this scene.

Also, the one with the confusion with the love letter, lol, classic.
