If the cats are good even if they don't believe in StarClan they go to StarClan, but the cats like the cats from BloodClan don't. I'm not sure about the cats that have never heard of StarClan, but are good. Even if some cats believe in StarClan, but they do some really bad things, then they go to the "Place of No Stars".
Yes, Lionblaze can go to StarClan after his death if he lived an honorable and just life, following the warrior code. StarClan is the afterlife for noble warriors from the Warrior Cats series.
(Actually, Hollyleaf didn't die. Well if she did die, everybody should know that she will go to Dark Forest.)It's unsure whether hollyleaf went to starclan or not. there has been no evidence that she is in the Dark Forest or Starclan.

No, Hawkfrost didn't go to StarClan. Due to his actions and alliances during his lifetime, he was deemed unworthy of joining the ranks of StarClan after his death. Hawkfrost's manipulative and ambitious nature led him down a darker path, leading to him being denied entry to the peaceful afterlife in StarClan.
Yes he did. You will see him there in Night Whispers. (Book 3 of Omen of the Stars)
