JK Rowling, when asked the same question in an interview, replied: "I think that when Dudley was attacked by the dementors, he saw himself, for the first time as he really was. This was an extremely painful but ultimately salutory lesson and began the transformation in him." Although, a few harry potter fanfics say that it was him doing Magic. I think this is more entertaining and causes some good fanfics. Just thought I'd add that in there.
When Dudley, his formerly mean and bullying cousin, shook his hand and said he did not hate Harry. This also shocked Dudley's mother. It was very unlike him to act kindly towards Harry (or almost anyone).
I can't remember if there are any dementors in the half-blood prince, there may have been some mention, but there weren't and serious scenes with them like when Harry fell off his broom or when he and Dudley got caught by them.
He was supposed to be Harry's protector, but he didn't do it so some Dementors attacked Harry and his cousin Dudley and then Harry used magic to make a Patronus which made him nearly get expelled from Hogwarts.
he used it to fight off the dementors

The third, Prisoner of Azkaban. And the fifth. And the seventh.

The dementors attacked Harry in #3 on the train to Hogwarts because Dementors feed on unhappiness and sorrow- Harry has a lot of just that [for one thing, his parents are gone.] The Dementors are not in their rightful home because they escaped.
No, dementors are foul creatures. There are no males or females.

There are no pixies either.

Yes, the dementors join Voldemort in Harry Potter and the Deathly Hallows.
The dementors make him remember of his past when voldemort killed his parents
Dementors don't actually exist so no there won't be.
