The ROI Manager plugin (Analyze: Tools: ROI Manager...) lets you
maintain a list of selections, but as distributed it doesn't let you
display all selections at once.
I did a modified version of ROI Manager several years ago that allowed
me to display and measure several different ROIs at once, but it
involved a lot of clumsy and heavy-handed modifications to other
classes (including, among others, ImagePlus), and so it wasn't really
suitable for release.
Would it work in your application to mark (Edit: Draw) each selection
after you measure it? It would modify your working copy of the image,
but at least you'd be able to see what you've done.
