Who were the main people accompanying Baba in the procession and what were their specific duties?

Sai Baba was surrounded by a close group of devotees who each had a specific role during the procession to the Chavadi. Chapter 37 specifies these roles clearly. Tatyaba Patil held Baba's left hand, while Mhalasapati held His right hand. Bapusaheb Jog performed the duty of holding a large umbrella over Baba's head. In addition to these three, there were two chowrie-bearers who fanned Baba from either side, a mace-bearer who walked ahead shouting Sai's name, and heralds who called out with love as the procession moved.
