jinchuriki

Also, could you list when they (or some, if all haven't found out) found out that he's the kyuubi (kurama's) container? I have a hunch (sorta) about when they could have found out, but just looking for confirmation. Thanks

after Gaara was ressurected by Granny Chiyo, Does he still have his tailed-beast sealed within him? or do the akatsuki have it now?
