AJ strikes me more of a Bearded tonfas or Mai Sok San fan. Not a hammer. Hammers are Big Mac's thing. Maybe Kanabo or Odachi or Dane Axe.
Twilight: Three Section Staff.
Rarity: Jian.

Dash: kusari-gama.
Cheerilee: Khakkhara or Monk's Spade. As befitting a teacher.
Trixie: Tengwar Rune Blade
Celestia: Jōjutsu. Simple, practical, versatile and unpretentious. Though grudgingly she keeps a fancy gilded ceremonial warhammer to keep her little ponies who expect nothing but the finest splendor from her happy.
Luna: A Qing dynasty Crescent Ji would be too obvious, methinks. I'd give her a runic Langseax.
Cadance: Archery would suit her just fine.
Shining Armor: Targe and sharpened Jitte. Both defensive-minded tools, but can still be used offensively.
Sunset Shimmer: A shiv or dirk or stiletto or an Assassin's Creed Hidden Blade. Or maybe a Renaissance smallsword to go with her Machiavellianism.
The CMCs: Sensha-Do.
