The vast majority of them have a cigarette lighter outlet which is continuously hot.

No. This will not damage your phone and will in fact make it charge faster.
No , just when the engine is running
The time it takes for a phone to charge is largely unaffected by whether the phone is on or not. It might be possible to argue that a phone that is on is using power from the charger to run the phone and to charge the battery, and therefore won't charge as quickly. But the contemporary chargers will generally supply enough power to charge the battery at the "prescribed" rate regardless of whether or not the phone is on. And they'll also supply the power to operate the phone while simultaneously charging the battery at the maximum (optimal) rate.
Of Course! You can preform any function on a phone while charging, including calling and texting!
Yes you can - it will just take slightly longer to charge.
not at all but if you dont use your car for a while and charge you phone inside its maybe possible but after a month or so if your battery is worn
The alternator - it provides a charge to the battery while the engine is running.
To charge a cell phone you will need either an outlet plug-in or car charger compatible with your particular model. The best way to fully charge a cell phone is to turn it off completely while charging. At the butt of the cell phone there should be a thin slot to plug your cell phone charger into. Plug the other end of the charger into your wall or car's cigarette lighter.
Cell phone models change quickly, and there is no guarantee the phone you have now will have new batteries available when you want them in a year or two. If you plan on keeping your cellphone for longer than a couple of years, it makes sense to invest in extra cell phone batteries while you can. Keep one extra battery on hand and swap it out once your cellphone stops lasting as long as you want it to last on a charge. If you haven't used it within a year, swap your batteries at that point to protect your charge.
