No, she killed Ashfur and she's dead now, so I don't think she will kill Firestar.
It is VERY unlikely since Hollyleaf has shown that she is loyal now and that he dies during the final battle meaning that most likely she doesn't, however it is never said that she won't.
Yes, he did. Erin hunter revealed in an online chat on wandsandworlds.com that both Firestar and Scourge had the same father, thus making them half-brothers. Firestar killed Scourge in the last book of the first series.
Ashfur betrayed ThunderClan by plotting to kill Firestar's kin - Hollyleaf, Jayfeather, and Lionblaze. He did this out of spite because Squirrelflight rejected his affection, and he sought revenge by manipulating events to frame her kits for a crime they did not commit. This act ultimately led to his own demise at the paws of Hollyleaf.
Hollyleaf kills Firestar because she believes he broke the warrior code by having a forbidden relationship with Sandstorm and fathering Leafpool's kits. Feeling betrayed by their family secret being kept, she is driven by her desire to uphold the warrior code and seeks to punish Firestar for his actions.
No. cause she is already dead, Tippygirl105 :) She is said to be still living and is to kill Firestar but we will find out. IT WAS CONFIRMED IN ERIN HUNTER SUMMER CHAT 2011 THAT HOLLYLEAF IS ALIVE AND SHE IS THE FORGOTTEN WARRIOR! (BOOK 5 OOTS)
Squirrelflight, leafpool, Hollyleaf, Jayfeather, Lionblaze, Whitewing, Cloudtail, Ivypool, Dovewing
Yes, it does. He is leader of ThunderClan and the grandfather of Jayfeather, Hollyleaf, and Lionblaze. He is also pretty important because the first time the prophecy is mentioned is in Firestar's dream.
No 'cause she is dead:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:It would be awesome if that happen (she's one of my favorite cat), but in "Sunrise" she goes crazy, and went into the tunnels and it collapsed on her. Well it doesn't tell you if she died or not. But in a warrior chat somebody said that 'Erin Hunter'don't plan to kill Hollyleaf yet. So look out because she might be back :p you never know.This is how I thought it would go:Hollyleaf becomes Hollystar, Lionblaze becomes a deputy, and Jayfeather becomes a powerful medicine cat.

No, Hollyleaf did.
It depends on what you think evil is. Hollyleaf does kill Ashfur though.
No, Hollyleaf does. It may seem like Squirrelflight did but she didn't 'cause Hollyleaf admits that she did kill Ashfur in Sunrise.
No. He does not.
