If you mean close friendship/love, the only cats I could think of would be Crookedstar (they used to be VERY close), Oakheart, Thrushpelt, maybe Stormtail (because Stormtail was her father), Moonflower (her mother), and Snowfur (her sister)
Bluestar is a Russian Blue
Snowfur was hit by a monster (car) when she was chasing ShadowClan cats. This took place in Bluestar's Prophecy.
You go to your page, click Avatar and choose one of the cats. You can choose Firestar, Bluestar, Cinderpelt and many more! Cinderpelt Bluestar

No, because there aren't any plans to make a movie yet.
I don't really know, but I think it is Bluestar and Spottedleaf.
You may be able to find a cat that looks like Bluestar from the Warriors series by visiting local animal shelters or breed-specific rescues, as there are many cats in need of homes with a similar appearance. Keep in mind that personality traits are also important when adopting a pet.
Bluestar's father, Stormtail, died in a gap during Bluestar's Prophecy. After Bluestar is made leader, she mentions Stormtail along with other cats who died when the clan ran out of prey. Stormtail most likely died along with these cats during leaf-bare.
We don't know. This is a better question to ask the Erin's. They were great cats but all cats have to go to StarClan. And without Fireheart becoming leader we don't know what would have happened to ThunderClan in the future.
From Thunderclan: Spottedleaf&Bluestar Riverclan: Silverstream Shadowclan: Yellowfang Windclan: Onewhisker
How ancient? When Bluestar was a kit, it was Hawkheart. The first WindClan med.cat was Mothflight.
Yes Bluestar lost a life in one of the books by rats..
