i have a problem executing this set of statements. it sort of hangs when i execute it. is there any other alternative ways i could do it by manually assign a standard size to the images to crop all automatically?

[I1c rect] = imcrop(handles.axes2);

rect

 axes(handles.axes2);
 imshow(I1c);
 guidata(hObject, handles);
 I2c = imcrop(I2, rect);
 axes(handles.axes3);
 imshow(I2c);
 guidata(hObject, handles);

The term "it sort of hangs" is not clear enough to be answered efficiently. Please explain exactly what happens (perhaps a complete error message?).

Select the pixels you want say for image I a cropped region will be I = I(1:x,1:y)

Don't use i (the imaginary variable) for a variable name. Not only that, but it's not a very descriptive name anyway. Use something like grayImage, or croppedOriginalImage or something like that. That way when you do image processing and have a lot of intermediate images that you may need to inspect, you won't have a confusing alphabet soup of short cryptic variable names.
