yes and so are Lionblaze and Hollyleaf.
Yes of course!
Yes Jaypaw is Leafpool's son. So are Hollyleaf and Lionblaze.
kinda,not really
Jaypaw was born blind.
He awesome!!!!!! Really? Because I just find him really grumpy. I think the question was asking who likes Jaypaw in the book. But ya he is awsome. When he was Jay's Wing, Half Moon liked him. But in his real self, it's possible that Willowshine and Cinderheart like him too. I agree too.
It was confirmed in Sunrise that Jaypaw/feather, along with Hollyleaf and Lionblaze, are indeed Leafpool's kits. Their father is Crowfeather of WindClan.
Jaypaw doesn't hate crowfeather he just doesn't like him.
We don't know. It does not say in the books.
Crowfeather
Leafpool
Jaypaw gains his full name in Long Shadows on page 253. His name is now Jayfeather.
Brambleclaw's mate is Squirrelflight for a while. Then he finds out she's lying about her "kits" lionblaze, jayfeather, and hollyleaf. who are really Leafpools kits. Hope i helped
