Quote #4
Ron and Hermione glanced quickly at Harry, as though expecting him to start berating Hagrid for not telling him the truth about Black. But Harry couldn't bring himself to do it, not now that he saw Hagrid so miserable and scared. (11.2.66)
It's interesting that Ron and Hermione seem to think that Harry's temper is so extreme that he'll go off on Hagrid even when Hagrid is clearly upset. Anger management classes might be in Harry's future, at this rate.
Quote #5
Harry knew that Hermione had meant well, but that didn't stop him from being angry with her. He had been the owner of the best broom in the world for a few short hours, and now, because of her interference, he didn't know whether he would ever see it again. (12.1.1)
Harry clearly tries to be sympathetic towards Hermione, but he can't quite manage it. The words used to describe the broom, such as "best" and "few short hours," make it sound like Harry just met and lost the love of his life. The narrator is sort of making fun of Harry even as the narrative sympathizes with him.
Quote #6
"Not Harry, not Harry, please not Harry!"
"Stand aside, you silly girl [...] stand aside, now [...]"
"Not Harry, please no, take me, kill me instead –" (9.5.45-7)
The scenes in which Harry has to listen to his mother plead with Voldemort are almost hard to read. Lily's desperation and fear, as she begs for mercy, come across powerfully here.
