Your first post left me with the impression that all the stores would have all the same products in them.
What you're talking about, while possible, is very complicated and prone to problems if not done well.
To do that is going to require a notable investment of time and custom coding.
And future upgrades will be ... well ... complex.
I really hope there's a lot more than just 5 products, else the amount of effort required isn't worth it.
Nevertheless, yes, it's possible. I wish you well !
