Each satellite team has nice web site. Some of them are in English.
Please refre to the URLs.
The satellites are not CubeSat. Size is bigger than CubeSat and platform
is unique.

The estimated orbit is
  orbit: Sun synchronous
  altitude: 660km
  inclination: 98.1deg
  period: 98min

I'v not seen keps elements yet.

  31x31x35cm, 28kg

STARS(Space Tethered Autonomous Robotic Satellite)
  KU (Mother Satellite) 16x16x25cm
  KAI (Daughter Satellite) 16x16x15cm

  15x15x15cm, 3kg

PRISM(Pico-satellite for Remote-sensing and Innovative Space Missions)
