how does the mechanical advantage of a pulley system change when increaIng the number of pulleys?

when one increases the number of pulleys the system efficiency decreases since each of the pulleys lose a certain amount of force due to friction. It is therefore typical that systems use multiple pulleys since a single fixed pulley provides little mechanical advantage.
