It means something that doesn't change, like a number.
Constant just means that the number does not change. For example, in Chemistry, avogadro's number is 6.022x10^23 and that number will never change, therefore it is a constant.
A constant in an algebraic expression is a number that does not change. For example x + 2 The 2 is a constant (does not change) x is a variable (can take on any value)
if a number can change randomly it is called a variable
It is the approximate number of feet per hour in one knot.
Constant is a number with no variables. For an example, 12a, but this is a constant 12.

A constant is a number that is always the same. Simple examples would be numbers such as pi, which is ~3.14159... Keep in mind though, while pi is endless, a constant doesn't have to be. It's just a number that doesn't change, so to speak.
Assuming that by "e" you mean Euler's constant and by "x" you mean multiplication of real numbers then yes.
If you add the same constant to each element of a sample then the mean of this collection of values will be the mean of the original sample plus the constant. If you multiply each element of a sample by a constant then the mean of this collection of values will be the mean of the original sample multiplied by the constant.
Yes - it is Avagadro's number/constant
It is constant for elements. IT depends on number of protons that atom has.
A [real] constant.
Vacuum, if maintained, is a constant as is the number 0 or zero and then there is the number 1
