> Can one learner do the same sequence multiple times?
A student can review the activities he/she has already done, but the activities will be already marked as completed.
If what you want is to the student to start from the very beginning again, the answer is no.
> I want to show my demo sequence to a number of people the same way the LAMS demo works.
You can create demo accounts for each students before hand. There's an option in the sysadmin menu that will allow you to import as many users as you like (and put them into a course) See:
So you can create all the users and put them in your demo course, add your lessons with all of them and then get them to login.
The other option is use the signup module which is not included in the LAMS official distribution and you will need to install separately: http://wiki.lamsfoundation.org/display/lams/LAMS+Signup
If you need help with signup, let me know.
