size of image3= 72 72 3
I get error for 2nd and 3rd image but not for 1st image

You're specifying 3 dimensions for trunCoarseImg but only two for coarseImg. You can't do that. You'd have to assign that 2D coarseImg image to each color plane in trunCoarseImg one at a time.

Hi Image Analyst,
How would you assign the 2D image to each color plane one at a time?

To assign the red channel (third index = 1), to some 2D array that has the same lateral dimensions (rows and columns), do this
rgbImage(:,:,1) = your2DImage;
