I posted them in the official forum:
Momiji gives a shuriken that causes slow turn, until it's ammo is gone, that is - this is nice, I don't like it personally
She also hands out wonderbits that work a lot like her FAIA!-balls and cause melt. This is nice in theory, but the HP of the bit are really, really, petit - it's hitbox is not petit.
Aila hands out her glacial sword. It requires some timing to utilize all of it's hits, the tracking is fabulous. This is nice.
Aila also hands out the Wolf Rid WB. Connecting it causes Wolfraid to show up in front of it's user. Wolfraid will then dash in the direction it is facing and damage/freeze people. This happens so fast that it is almost like WB dodging, except that you sacrifice your entire gauge for it. I think it is reliant on TEC/STR balance, so it's crap.
Shana hands out a replica of her circlet thing. This is adorable.
Shana also hands out the Pushpaka bit. This works the same as Wolfraid, except it doesn't freeze things. Very much to my surprise Pushpaka is dropping down rather then dashing from the altitude it was summoned at. I tested this one and you can not pull it of properly if there's no TEC/STR left.
Lala hands out a replica of her main weapon in form of an LGJ. Lala's main...
Lala also hands out her "main" as a WB. The speed seems a little faster than the real thing. I think it isn't bad, but you have better, more stable options (Dual Rifl Bits in example).
