In a runners sweat there is water and presperation to keep the runner cool.
There were globules of sweat on the runner.
A runner's sweat primarily consists of water and electrolytes such as sodium, potassium, and chloride. It may also contain small amounts of waste products like urea and lactate. The composition of sweat can vary depending on factors such as fitness level, temperature, and hydration status.
Perspiration (sweat) is generated by the body in normal circumstances to act as a cooling system. When a sports person, in this case a runner generates above normal temperature the body's sweat gland are triggered to produce sweat. The effect of air on the wet areas of the body act as a cooler.
Because sweet is the body's function to cool you down. The runner could overheat and pass out.
Yes, sweat suits are good to wear for running. As long as you are comfortable, then you are all set.
Uh...personally...I think saliva. But that's only because I'm a runner and I don't mind sweat.

It will depend on what you mean. There are some materials that will help with wicking away sweat (technical clothing), and there are pants that have liners (to absorb the sweat).
For the runner to cool

Deodorant is spread into the armpit to help mask the smell of sweat. They do not cause your armpits to sweat less, though. Antiperspirants plug the sweat glands up in your armpits so that you do sweat less. Most antiperspirants also have a deodorant in them as well, to not only help you to sweat less, but reduce any odor caused by the sweat in your armpits.
