Drawing Classes at home

I stay in multi storey complex in Andheri, Mumbai. Flat above me conducts Drawing classes for children and sell spices and Dryfruits. Children coming there for classes keep running else there is constant banging on floor due to which there is continuous nuisance to me. All these activities are obviously at consideration. Can I please know the following : 1. Do laws permit conducting such activities at home ?; 2. Shouldn't such Flats be charged extra maintenance as in afternoon lifts only move multiple times between Ground Floor and their Floor as many Children go to their Flat at the start and then go down when classes end. There are multiple batches during the day. Why should this increase in electricity Bill due to lift movements be borne by other residents like me ?; 3. What are the Penalty Clause for such troublesome Residents ? 4. What is the option available to me if they continue creating trouble(noise) even after I have got to notice of Society and still they do not improve.
