Hi, I am working on images with crowded objects with various circularity and sizes. Is there any way to detect and list all their shapes and sizes (grouping ones with the same area, and grouping ones with the same shape after)? Any answer is appreciated.

Sure. I do that in my Image Segmentation Tutorial http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862&sort=downloads_desc
For example:
props = regionprops(labeledImage, 'Area');
allAreas = [props.Area];
bigAreaIndexes = find(allAreas > 10000); % Blobs with an area > 10000 pixels.
% Extract only the big area blobs:
bigBlobs = ismember(labeledImage, bigAreaIndexes);
Similar for circularity or any other measurement.

A look at what? You forgot to post your image.
