They are variables, unknowns, values that can be anything, any number. They are used to represent general values.
Eg:
3x+y=1
here x and y are called variables. One possible value for x is 0 and for y is 1. If you put x=0 and y=1, you get 1 as the answer, that on the other side of the equal sign. Other values are 1 and -2 ; 2 and -5 and so on. x and y are the variables that represent generalised values.

Letters inserted into a equation to represent variable or unknown values are correctly referred to as variables.

They are usually called variables and sometimes parameters. Variables, exctly as the name suggests, varis; and the parameters, though they influence your model, are considered fixed.
When variables appear in equations, they are also called unknowns.

They are called "unknowns" or "variables".
