That would require you to differentiate within htaccess what is a user and what is a group. I don't think that this is an option in your case since (I guess) your user and group names will be dynamic and stored in some kind of DB.

Thus, you'll have to solve the problem in PHP. You could do some rule like this:

RewriteRule ^([a-zA-Z0-9_-]+)$ userOrGroup.php?parameter=$1

and then, userOrGroup.php redirects to either profile.php or groupProfile.php (or whatever your group pages are called), depending on whether the parameter is a user name or a group name.
