In the Malankara Syriac tradition the most common that I have observed is :
'Ninth Hour', 'Evening' , and 'Bedtime(soothoro) all prayed together in the evening around 7pm. The prayers used is the 'Pampakuda Namaskaram' which is simplified form of the Syriac shimo. The English translation can be seen here:http://sor.cua.edu/Liturgy/SimplePrayer/BedTime.html
This is fairly common and most religious Malankara Christians know these prayers (9th hour, evening and soothoro) by-heart and recite them without the help of a prayer book.
The entire Morning prayers from the Pampakuda Namaskaram prayed daily is not that common. My grandmother and mother used to. For the rest of us in morning it is only the Qawmo (http://sor.cua.edu/Liturgy/SimplePrayer/Qawmo.html
) and the Nicene Creed. I have never seen a lay man from my family pray the Third or Sixth hour daily.
