who became the first speaker of 32 member hp vidhan sabha of 1952

There seems to be a slight discrepancy in the information provided. The Himachal Pradesh Vidhan Sabha (Legislative Assembly) constituted in 1952 actually had 36 members, not 32.

However, we can still answer your question about the first speaker.

The first speaker of the 1952 Himachal Pradesh Vidhan Sabha with 36 members was Pandit Jaiwant Ram. He served from 1952 to 1956.
