Critical Mach Number, or Mcr, refers to the lowest Mach number that air going over and around an aircraft can reach the speed of sound. If an airplane goes over its Mcr, handling might be greatly affected.
it is ,free stream mach number for which the entire flow over a body is supersonic..

Mach number
Mach is the speed of sound in that medium, and is known as Mach 1. It will vary according to pressure and temperature. [More correctly, it is the dimensionless number relating the speed of an object to that of sound in that medium.] Mach does not have units associated with it, such as mph or kmph.
'Mach ' is the speed of sound. This depends on air pressure and temperature. On a median day at sea level this is normally 761 mph. That figure can vary if air conditions are changed, but based on this common number, mach 4.5 is 3,324 mph.
Critical Mach Number has nothing (directly) to do with altitude. Mach Number has everything to do Temperature,
Lower critical mach number may be defined as the highest subsonic mach number below which the entire flow over it is subsonic. vijayaprakaash
The critical Mach number will increase significantly

Mach Punch is not a TM so therefore it does not have a TM number.
At high speeds and altitudes
Mach number is dependent on a number of factors. Factors such as air density or altitude will change the Mach number. At approximatively 45 000 ft Mach 0.85 =289.2361 m/s = 1041.25 km/h = 647.0028 mph
Mach No at throat = 1.0
The mach number is the speed of an aircraft, expressed as a fraction of the speed of sound in the atmospheric conditions in which the aircraft is flying. An aircraft flying at mach 1 is flying at the speed of sound.
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.
The "Mach number" is the speed of the aircraft as a percentage of the speed of sound. So an aircraft going at Mach 0.74 is traveling at 74% of the speed of sound. (Mach 0.74 is a typical airliner speed.)
