I just found the following info on the web.
Jim Nabors is 82, living in Hawaii, and is the last adult cast member.
Of course, Ron Howard (Opie) is doing well.

Here are the ladies still around:
Betty Lynn, who played Barney's girlfriend Thelma Lou, currently lives in Mount Airy, N.C. It was Andy Griffith's birthplace and widely believed to be the inspiration for Mayberry. She makes monthly appearances on the town's Andy Griffith Museum on the third Friday of the month.

Elinor Donahue, who played the town pharmacist and Andy's girlfriend in the show's first season, continues to work occasionally. She most recently appeared on several episodes of the soap opera "The Young and the Restless" in 2010 and 2011. She lives with her third husband, retired Broadway actor and dancer Lou Genevrino, in the retirement community Sun City in Palm Desert.

Maggie Peterson, who played Charlene Darling in several episodes of the series, married jazz musician Gus Mancuso and settled in Las Vegas, where she worked for many years as a location manager for film and TV. She's a regular attendee of the Marshfield Cherry Blossom Festival in Marshfield, Mo.
