How can I apply Matlab code to do what the imcrop function does but manually using for loop?

Not sure what you mean. How about this
grayImage = imread('moon.tif');
figure(1)
imshow(grayImage)
for k = 1 : 3
uiwait(helpdlg('Drag out a box to crop the image.'));
croppedImage = imcrop(grayImage);
figure(2) % Switch to a figure just for the cropped images only.
subplot(2, 2, k);
imshow(croppedImage); % Display it.
figure(1); % Return to the original image.
end
