If it is civil , its mach 1.- mach 2 ,name is Concorde & in defence they go beyond mach 2
The top speed of an airplane can vary by the model of the plane. The highest speed ever reached was 2,193 miles per hour by an SR-71 Blackbird in 1976.

Airflow ans lift over the airframe is affected by the airplane's speed.
The Blackbird
This question can't really be answered with a single speed. Each airplane is different to another and is able to reach different speeds. A small business jet like for instance the Cessna Citation X is able to reach speeds up to Mach 0.95 (that is 0.95 times the speed of sound).

The speed of sound does not travel. In the event that an airplane's airspeed is below Mach-1, the speed of sound is faster than the speed of the airplane. On the occasion and at the moment when the true indicated airspeed of an airship or an airplane is in excess of Mach-1, the airplane is at that time traveling faster than the speed of sound.
Wing plays an important role in the speed of an airplane. A headwind reduces the speed of the aircraft. A tailwind increases the speed of the aircraft.
The speed of a commercial airplane is about 0.8 mach
It is believed that the speed of light is the highest possible speed.
The manned airplane that has flown the highest is the Scaled Composites SpaceShipOne flown by Brian Binnie. The airplane was launched from another aircraft on October 4, 2004 and reached a height of 367,441 feet.
