It would very unlikely, probably impossible, to damage a mower by starting it with it still on the charger
probably not but it is possible. Things like Hydrogen gas and big bangs due to charging the battery.
Not exactly "damage", but if you keep it on the charger all the time, then the battery capacity may appear to decrease, i.e., the battery won't last as long when you do use it. Think of the battery as a muscle.
Plug in whatever charger it uses :) But seriously, modern Li-ion/polymer batteries need no hocus-pocus. No need to format them, or anything, and no memory effect to speak of either. They can be trickle-charged, so leaving them on the charger doesn't damage them. Charge them, use them, and when you see that the phone will not last another day, recharge.
Theoretically no. Most chargers have a 'feedback' loop which detects when the device has been fully charged. This puts the charger into 'trickle charge' mode. However - it's not a good idea to regularly exceed the charging time, as eventually it can damage the battery.
no, but it will damage the battery.
Starting torque becomes very high due to which motor can attain very high speed and can damage its body and connected equipments.

Yes, an 18 volt charger can damage a 14 volt battery. This is because the wattage for the battery needs to be equal to the wattage of the charger.

Yes it is in principle, but two things have to be checked. First if it is nominally 12 volts, it might not produce exactly 12 volts, and this needs to be tested so damage is not done to whatever is connected. Secondly, the adaptor/charger has to be able to supply enough current (amps) for whatever you are connecting to it.
