if i make a figure out of mmf, how long can i store it?

Forever! I still have the figurines I made on my wedding cake and that was 6 years ago. They have faded a little, but still all in one piece. I just keep them in an airtight container with a small sachet of silica gel (like the packs you get in new shoe boxes).
