She is actually the half-sister of Breezepelt. Breezepelt's mother is Nightcloud, and his father is Crowfeather. Hollyleaf's father is also Crowfeather, and her mother is Leafpool.
Breezepelt from WindClan.
Hated them
The answer is unknown. Some people have ideas though. But from the warrior books, he probably hates Hollyleaf, Jayfeather, and Lionblaze since they are half clan.
Crowfeather's kits are Breezepelt, Jayfeather, Lionblaze, and Hollyleaf.
Well there certainly is a pattern to the warrior books. Firestar killed his half brother Scourge and Brambleclaw killed his half brother Hawkfrost so Jayfeather or Lionblaze will kill Breezepelt. I would think mabe even Leafpool will kill Breezepelt trying to save Jayfeather or Lionblaze because she loves them and mabe Breezepelt set up an ambush or trap. Moonshadow & Icecloud:)

No he does not, because he knows they are kin. Starclan told him but he was told not to tell anyone
'real brothers': Jayfeather and Lionblaze. Half brother: Breezepelt (rogue, originally from WindClan)
Crowfeather has a strained relationship with his son, Breezepelt, due to past events and misunderstandings. While their relationship is complicated, Crowfeather does care for Breezepelt deep down, but their issues make it hard for them to fully connect.
Yes, Nightcloud is Breezepelt's mother in the Warriors book series by Erin Hunter. Nightcloud is a WindClan warrior who had Breezepelt with Crowfeather when he was in a brief relationship with her.
Yes, Breezepelt attempted to kill Hollyleaf in the Warriors series. He was manipulated by Dark Forest cats and held a grudge against the ThunderClan warrior because of their past conflicts.
