Can you provide details about the group of devotees from Madras mentioned in Chapter 29?

Certainly. Chapter 29 describes a group of devotees who came from Madras (now Chennai) to Shirdi for Sai Baba's darshan while on a pilgrimage to Kashi. This group's fame had spread in their region, and they were followers of the Ramdasi sect. They performed devotional singing with great enthusiasm and stayed near Sai for several days. According to the narration in Chapter 29, Baba gave them eight rupees and eight annas, which pleased them, demonstrating his generous yet selective nature. The text also mentions another group of four—a man with his mother-in-law, wife, and daughter—who came seeking the saint's darshan.
