Who were Sai Baba's earliest companions in Shirdi, and what kind of service did they render?

According to Chapter 0, after Mhalasapati welcomed Sai Baba into the Khandoba temple, he brought him into the village and introduced him to his companions, Kashiram Shimpi and Appa Jagle. These three men—Mhalasapati, Kashiram, and Appa—became Baba's devoted followers. The text mentions that it was their practice to serve and look after saints and fakirs who came to Shirdi, providing hospitality according to their means. All three became total devotees of Maharaj, with Kashiram in particular serving him excellently with his body, mind, and wealth.
