Stamina is your endurance. For example, the more you run, the longer your stamina will be. It relates to fitness because the more stamina you have, the longer you'll be able to participate in athletic activities.

The four S factors in fitness are strength, stamina, suppleness, and speed. These factors encompass different aspects of physical abilities needed for overall fitness and athletic performance. Incorporating exercises that target each of these factors can help improve one's overall fitness level.

It depends on how you would define "yoga". In western society, yoga is mostly understood as a system of a certain type of physical exercises aimed at relaxation and suppleness. To me, this is a too confined view. Yoga is in fact a philosophy of life. However, physical fitness is highly valued in yoga (as the body is regarded as the vehicel of the soul). But relaxation and suppleness aren't enough. You should also work on aerobic and strength (if you just want to be in a good shape). In my opinion, Dan Millman's "four S's of psycho-physical talent" provide a good guidline (these four S's are strength, suppleness, stamina, sensitivity)

The basic 'forms' of fitness are suppleness (flexibility), stamina (how long you can do an excercise for), speed and strength. These are sometimes refered to as the 4 Ss. Health in terms of diet or of fitness are different. You can eat more than average compared to your age group and still be fit, or do lots of excercise and still be overweight. It just depends on whether you burn at least as many calories as you consume. Sorry it's not a great answer or anything :-] I'm not that sure if I understood the question...
Like all martial arts, it improves conditioning. In addition to building strength, it promotes flexibility and stamina.
