Use stabilized chlorine only so long as stabilizer level (cyanuric acid level) in pool is within the recommended range of 50-80ppm.
Sunscreen and granular chlorine mixed in the water or a bucket should not be a problem but if you get granular chlorine on your skin make sure you wash it off quickly or you can end getting a chemical burn (much worse than a sunburn)
You should always maintain "normal" chlorine. Shocking a pool consists of adding a large dose of pure liquid chlorine. This kills any algae (and othe rmicro-organisms). The chlorine is not stabilized, and will disspate within a day or so.
Sure you can use liquid chlorine and walk around the pool. You can use granular chlorine directly into the pool. If it doesn't disolve before it gets to the bottom you should brush it around so it won't stain. Never add pucks/tabs directly to the pool OR THE SKIMMER. (BAD FOR THE EQUIPMENT) They will sink to the bottom and stain.

Watery chlorine should be protected from sunlight.
pH and sanitizer should be checked daily in a perfect world...at least 2-3 times a week at minimum. TA every week, CH weekly to monthly, depending on the hardness of your fill water. CYA weekly to monthly, depending on whether you use a stabilized chlorine source or an unstabilized chlorine source such as a salt water chlorine generator or bleach/liquid chlorine with periodic stabilizer additions. How frequently you need to check CYA also depends on whether you ave a non backwashing filter (cartridge and some DE filters) or a backwashing one (sand and some DE).
Should chlorine tablets be used in place of stabilizer chlorine tablets so the cyanuric acid don't get to high?
The first thing you should do for a chlorine gas victim is to remove him or her from where the chlorine gas is. Giving the patient first aid for inhaled chlorine does no good if the guy is still lying there breathing chlorine.
NO you should never have chlorine in with your guppy it could hurt the fish
Cl is an abbreviation for "chlorine" you should check free chlorine and total chlorine for comparison.
