I'm fully confident that Rand's Facebook likes are genuine.
We started tracking the Facebook stats of Ron, Rand and various potential 2016 candidates starting just after the 2012 election in this thread:

There's a summary on the first page that tracks Rand's growth over different dates, and throughout the thread I posted charts and graphs.
You can see that his numbers grew over time, with spikes around the drone filibuster and other events.
Also, a page with an inflated number of fake likes would lack activity on their posts... and Rand's have always done well. His original posting of his tax video from the 18th is nearing 2 million views, 40k shares and 30k likes.
For the age part, unfortunately Facebook doesn't publicly display as much info as they used to so we don't know what it is today... but in that thread I noted that the largest age bracket for people that liked Rand's page was 55+.
