numPixels = cellfun(@numel,CC.PixelIdxList);
numPixels =
1015 951 719 852 760 550 503
I want to sort this value and their indexes also. how can I do this?

Not sure who told you that convoluted complicated way of determining the number of pixels in the labeled objects. You can do this so much easier by doing this:
props = regionprops(CC, 'Area');
sortedAreas = sort([props.Area], 'descend'); % Areas = "numPixels"
