iPods do not support email - they are mp3 players.
Yes but they have too usually be from 2 different iTunes accounts..
same as normal
Yes you can use the same ID. It's not a good idea to let someone else use your ID though as they will be able to use your details to pay for apps etc. If you, yourself, have two iPods and wish to use the same ID then this is a lot safer.
Of course you can.
No two people can have the same gmail address. If there are 2 accounts, there will be 2 different email ID's. The Facebook account will be different in that case too.

People use iPods a lot. Sometimes they listen to music while they run or walk, watch a movie in the car or airplane. And if they have an iPhone they check email, surf the web, talk, and text.
