Going off the theory that the tailed beasts produce unique substances other than their "advanced" natures...

(Italics for unconfirmed)
 * Shukaku: Substance: Sand - Natures: Magnet Release (Wind + ???)
 * Matatabi: Substance: Blue flames - Natures: ??? (Fire + ???)
 * Isobu: Substance: Coral - Natures: ??? (Water + ???)
 * Son Gokū: Substance: None - Natures: Lava Release (Fire + Earth)
 * Kokuō: Substance: Steam (if not Boil Release) - Natures: Boil Release? (Water + Fire)
 * Saiken: Substance: Alkaline fluids - Natures: ???
 * Chōmei: Substance: Scale powder? - Natures: ???
 * Gyūki: Substance: Ink - Natures: ??? (Lightning + ???)
 * Kurama: Ability: Senses negative emotions - Natures: ???
 * Ten-Tails: Substance: Plants (if not Wood Release) - Natures: Wood Release? (Earth + Water)

As a form of the progenitor of chakra, Ten-Tails and its jinchūriki probably have all natures, but I listed Wood Release since it's highly unlikely any other tailed beast uses it. That just leaves Storm, Scorch, Explosion, Ice, possibly Blaze, and 1-2 unknown natures (unless Kurama really has nothing). That's assuming none of them use Dust either.
