I have one doubt that, suppose if a matrix has zero mean and unit variance, then whether each of its columns has zero mean and unit variance or not..?

What is the "mean" of a matrix exactly? I do not think that this is mathematically defined.

No. Take the matrix
A=[1 -1; 1 -1]
Clearly A(:) has zero mean and unit variance, but its columns individually do not.
