Or is there anyway we can Integrate Avatars and USer Profile with Alpha User Points Profile?
As far as I know, Alpha User Points extension just provides points for whatever user system is used on the site, it doesn't bring its own profiles and avatars.
I understand what you want, but I'm not sure what to suggest. Joomla's default user system has a very limited support for user profiles, so some extension for user profiles is required if you want to have them. JomSocial is the most popular, but it brings a huge number of community features that most people don't need.
JReviews provides integration with Community Builder and Kunena as well, but they aren't much better.
