Yes, although Coca-Cola Zero has no Calories, Sugar, or anything considered "bad" for you it does have some caffeine.
Coffee beans are naturally caffeinated so the existed caffeine must be removed, i.e. de-caffeinated. Cola (Coke, etc) often has caffeine added as a separate ingredient, so if that ingredient is skipped, the cola is free of caffeine.
Look for the word "Decaffeinated" or "Decaf" in the packaging. Do note that even though most of the caffeine in decaf have been removed, not every decaf brand will be 100% caffeine-free.
Decaf can contain anywhere from less than 1% to about 3% of the caffeine of caffeinated coffee. This is because it is easy to get most of the caffeine out, but very tedious to get just about all of it out. This amount of caffeine should not have an effect on people, however.

Caffeine free has no caffeine and regular still has caffeine and sugar!
Just like decaf coffee, decaf tea does contain a small residual amount of caffeine. The caffeine content will depend on the company producing tea and the process they use, as well as on the original tea's caffeine content. Apparently the High Pressure Carbon Dioxide Process developed in Europe produces the best decaf tea as it removes most of the caffeine, does not leave any residual carbon dioxide and extracts less of the flavor. However, no decaffeination process is perfect, and all decaf tea loses some flavor. People who want a truly caffeine-free drink that resembles tea will need to drink naturally caffeine-free herbal teas.
Yes - cola drinks contain caffeine.
Herbal teas generally have no caffeine naturally, they do not have to be decaffeinated.
Decaf and regular caffeine products can cause dehydration. This is due to the fact that even decaf products have a trace amount of caffeine. The caffeine is directly related to the body flushing out its sodium-bound water reserves through the kidneys.
