The easiest way I can think of is to append the entries from multiple images into a single table in a loop and then write that table to an excel or csv file. The following code illustrates this idea:

I{1} = imread('coins.png');
I{2} = imread('cameraman.tif');
final =table;
for id=1:2
    data=regionprops('table',I{id}, 'Area', 'EquivDiameter', 'Centroid', 'MajorAxisLength','MinorAxisLength')
    final = [final;data];
end
writetable(final,'mydata.csv')
