why not? if you can insure 2 houses at different addresses then these are 2 cars at different addresses. will have to check though. Try different insurers
Ethernet addresses are 48 bits long - not 32 bits long like IP addresses. Different single network standards have different address lengths. Ethernet addresses are called MAC addresses for other reasons, Media Access Control.
Yes.

I think you are mixing up two different protocols. IPv6 addresses are not hard coded into your adapter; MAC addresses are. It's totally different. IPv6 addresses are 16 bytes long and MAC addresses are 6 bytes long.
These hidden addresses can be used many times in many different organizations. This way different organizations can use the same address range and not collide with other networks.
To create different Facebook accounts, you must use different email addresses, no matter what computer they are created. The only way to know if a person is using different accounts is to know their different email addresses. Or ask them.
yes
People have different ip addresses
yes
It should not cause any problems on the network since the first 24 bits of the MAC addresses are different.
