Rickey asked, "I am wondering if you have any dances for low numbers of dancers
(perhaps 6 or less), when most or all of the dancers are beginners and adults.
I am also wondering if you have any dances (presumably different dances), that
do not require choosing a partner and are good openers for beginner adults."
I've missed some of this discussion, so apologies if I'm repeating. There are
many good possibilities to be found in the English ceilidh repertoire. One
useful source of such dances is Thomas Green's website:

Now, granted, 6 or less is a pretty small number of dancers, and many of the
dances on this site need more than that, but there are plenty that will work
well for the situation you describe.
Triplets, of course, are a helpful part of your repertoire. With five people
there, you can join in to make up a triplet, and that will keep your dancers
moving for quite a while. They range, of course, from simple to very
challenging, so pick carefully. One that you might find appropriate for this
situation is David's Triplet #4," by David Smukler, which was written
specifically to be relatively simple:

Good luck!
