Yes.
The order of a matrix is another way of saying the dimensions of of a matrix. For a two dimensional matrix, the order could be 2 by 2, or 3 by 3, or 32 by 64.
It will be a 2 x 5 matrix.

Yes.
No. Matrix addition (or subtraction) is defined only for matrices of the same dimensions.

No.Two matrices A and B can be added or subtracted if and only if they have the same number of rows and columns. That is a 3 x 2 matrix can be added or subtracted only with another 3 x 2 matrix.
