Mach I (the Speed of Sound) is approximately 1,236 km/h (738 mp/h). This is dependent on the air pressure. At sea level, the speed of sound is about 760 mph; at high altitude it reduces closer to 600 mph.
A Stinger missile has a speed of around Mach 2.2, which is roughly 2,685 km/h or 1,670 mph.
Mach 1.8 (1,191 knots, 2,205 kph) source Wikipedia
The crusing speed of the concord jet is Mach 2, or 1,336 mph (2,150 kph).
Mach 3 = 2283.6211 mph
Mach 3 is 2283.6211 mph because Mach 1 equals 761.207033 mph.
The mach number is the speed, compared to the speed of sound in air. Thus, mach 1 is the speed of sound, mach 2 is twice (2 times) the speed of sound, mach 3 is 3 times the speed of sound, etc.
500 mph = 804.7 kph

For an Exotic read "The AURORA Program" sees the stealth aircraft evidence supporting Mach 8 and beyond. It would depend on the jet itself. Each jet has a different engine (thrust production), weight, lift and drag component which all effect the top speed of fighter jets. For example the f18 hornet has a top speed of mach 1.8 (1190 kph) whilst the yet the mig 35 can get to mach 2.25(2400 kph)
Mach 3.6 = 2,740.34 mph
