You can read what you wish to read without any restrictions as long as you are not leading others.

What is the minimum verse of long Surah to be read in prayer? E.g. Can I read Surah Mulk (complete) in the 1st rakaat and then 30 verses of Surah Rahman in the 2nd rakaat? Or is it makroo to read more than 3 verses from long surahs?
