This code that I wrote only makes 2 masks. I would be grateful if someone modifies the code so that they can make as many masks as they want.
If there is a code prepared for this purpose, please help

The way you're doing this is causing objects to be overwritten.
You can use the same method I showed in your prior question.
im = imread("coloredChips.png");
numROI = 6;
% create ROI objects and adjust them
imshow(im);
for k = 1:numROI
h(k) = drawassisted(gca);
end
% wait until the user is done
input('Press enter when done adjusting ROI objects');
% build mask
mask = false(size(im,1),size(im,2));
for k = 1:numROI
mask = mask | createMask(h(k));
end
