I think this should be straight straithforward supposing you know how to read images.

Mat image1 = imread("location_image1"); 
Mat image2 = imread("location_image2"); 
vector<Mat> various_images;
various_images.push_back(image1);
various_images.push_back(image2);

With this code you can create loops of your desire!

UPDATE:

And to access elements of your matrix, it all kind of depends what type of matrix you are using but in the case of a matrix of type CV_8UC1 you can use the command

int currentElement = image.at<uchar>(row,col);

If you have a multi channel image than first use the split function

UPDATE 2:

Access of a vector is done by

Mat retrieve_element = various_images[index];

where index is a number between 0 and amountElements-1
