It depends on the current required by the coils on the relays. The sum of the coils currents must be less than the 555 output current rating. (Which according to the data sheet is 200 mA.)

How many relays can be operated with single 555 output.
With the help of a Mosfet, many. Driving relays directly with a 555, usually just one.
