The subscript value of a chemical formula is used to represent the actual number of atom present in the original compound . The compounds name is Naphthalene and the subscript value represent the original number of atom present in the compound. The subscript value remains same for the compound. If the sub scripted value change it becomes another compound.  From the sub scripted value Naphthalene has 10 atoms of carbon and 8 atom of hydrogen.  

The coefficient value is used  when balancing a chemical equation or to show the number of moles of the actual compound . The 4 depicts that the compound has four moles of Naphthalene. If the coefficient value is changed the compound still retains it name but the quantity is altered in moles. Example  5C10H8 is five moles of Naphthalene.
