Unfortunately, a F2P squad is hard to clear Grahdens's Grand Quest, especially the final boss of the quest. Besides, most players would've cleared Trial 004 by the time they get to Grahdens's Grand Quest.

However, 6* Grahdens may be used as a friend for this Trial. In that case, a squad like this would be ideal:


 * Grahdens


 * Ice Legend Selena


 * Sacred Armor Nevsky


 * Radiance Sibyl Sola


 * Dark Legend Magress


 * Twilight God Grahdens

Unfortunately, this means that you will need to pack Stimulants and Holy Waters and strategize how you are going to use them, unless you are giving everyone Refined Gems, Cosmic Dust, or the like.
