Bramblestar died after being possessed by an imposter posing as the spirit of Ashfur. The imposter caused chaos within ThunderClan by manipulating Bramblestar and ultimately leading to his death.
Bramblestar loses his lives in "Warriors" series by being injured or killed in various battles, conflicts, or accidents. Each time Bramblestar dies, he loses one of his nine lives, which is a concept in the series where leaders of the Clans have multiple lives to serve their Clans.
Probably yes
Bramblestar
Im pretty sure that it will show thunderclan since the title is Bramblestar "star" so it must mean after he recieves his nine lives.
Squirrelflight is not infertile. She and Bramblestar have kits together in the Warrior Cats series.
In Bramblestar's Storm, her mate is Bumblestripe.
WARNING SPOILERS! I don't believe so because in the one of the last two books in the Omen of the Stars series Brambleclaw will be blinded.
Firestar has not died yet but he has lost 7 lives.
