You could but is it a total waste of money and is overkill. Use 12/2 with ground on all 120 volt outlets and light switches.
Assuming this is not an office of a place where lots of the outlets will be used to power items that draw lots of current on a 15 amp circuit wired with 14/2 wire I would limit it to no more than 10 outlets and lights combined. On a 20 amp circuit wired with 12/2 wire I would limit it to a 14 outlets and lights combined. There is no limit in the code. You just use common sense based on what is going to be used on this circuit.
A 30 amp breaker is usually used for a dedicated 30 amp device. Ordinary 15 amp receptacles can not be connected to a breaker of higher trip capacity than the rating of the receptacle. The wire size for a 30 amp breaker is #10 AWG.
US homes use a 240 volt single phase 'Edison' system. It is a 3-wire (4 with the ground) system. Phase to phase measures 240v, while each phase to neutral measures 120v.
Yes it is wired with copper 2 wire is also known as 14/2 wire is use for switches,outlets,lights. and a 15a outlet should only be on a 15a breaker the main power feed to your meter to your panel is aluminum and can take more of a load than copper. In the US, 15 amp receptacles can be installed on 20 amp circuits if there is more than one receptacle on that circuit. Copper wire can carry a larger load than aluminum wire of the same size.
I would install a 60 amp sub-panel and use AWG #3 copper.
All the lights and electronic equipment that use wall outlets in your home.

It is unusual to have multiple outlets on a 30 Amp service. If you do this you need outlets rated at 30 amps and 10 AWG wire.
The only determining factor is the size of the circuit breaker that you will be using. If the garage circuit will be protected with a 15 Amp breaker, you may use a 14 AWG wire. If the circuit will be protected with a 20 amp breaker, you must use a 12 AWG wire. Note too that garage outlets should be protected with a GFCI breaker or outlet. If you have any concerns regarding your ability to adequately design and install the garage outlets, please, for your own safety, contact a local electrician.
A. It's 240 volts & B. Wire size is a function of amperage. 12-gauge wire is used with 20 amperes or less. So, 12-gauge wire can be used with 120V/20A or 240V/20A. Keep in mind though that 240V in the U.S. has 2 live 120V lines so if you encounter a white wire, it's probably an unmarked live & should be repainted as black or better yet, red (to indicate the 2nd live wire).
Ring connection of socket outlets? Have no clue what you mean by this. Please rephrase the question in terms that are understandable. I will venture to guess as to what you mean. If you mean what is the advantage to connecting more than one outlet on a circuit the answer is to save wire and to allow the installation of over 100 outlets in a home on maybe just 10 circuits depending on the use of the outlets.
no
Yes.
Use a 15 amp breaker and 14 AWG wire and all switches and outlets rated at 15 amps or greater.

you dont!! indirectly, via your electric outlets.
Yes, anytime your see a glowing wire inside the light it is an incandescent lightbulb
