imcrop should have a rectangle as input, but you have a mask. You could use

roi = drawrectangle();

instead of imfreehand and then change imcrop to

I = imcrop(I,roi.Position);

Error in I=imread(images(1).name);

If you want help I need a bit more than that.

You need to prepend the folder since the images are not in the current folder:

fullFileName = fullfile(images(i).folder, images(i).name);
I = imread(fullFileName) ;   % Read image
