That is very hard to tell. You will have to study their genitals (really!) with a microscope. In general males are larger than females.
There is no way to tell the exact age of a cactus. Unlike trees you can count rings, but for cacti some believe like the saguaro cactus you can use the arms to tell the age, but in the life span of a saguaro it can grow at different rates. if you have to estimate a saguaro it takes the base an average of about 60 years to grow to the size of a male adult.
you usually have to have a low powered microscope or a really good magnify glass.
