Northern Ireland is part of the UK so you need no ID to travel there. In fact since the UK and Eire are in a common travel area so you need no idea to travel anywhere within the British Isles. However since the war on terror, many airlines will require you produce ID, However there were no such caveats during the troubles.
I'm almost positive about that. You need a passport if you want to travel to a different country, so most likely yes.

Not between the UK mainland and Northern Ireland, which is British so not a different country, unless the ferry company insist on passports for their own security (as happens for internal flights within the UK). You may need one to travel between the Republic of Ireland (Eire) and the UK as that is a "different" country.
NO. But under the requirements of European law and the Athens convention, you are required to disclose certain details about you. You will need a passport or identification.
You need a passport when traveling from any country to another.
That will depend on your nationality. Irish or British citizens wouldn't necessarily need one. As a general rule though, for any international travel, bring a passport with you.
No, but you do need I.D.
No
no - it's an internal UK ferry trip
Yes you do, even the travel to Ireland from the UK has now been restricted to passport holders only.
I am a british citizen living in northern Ireland and I am attending a wedding in Scotland. I intend to travel to Scotland to the wedding by ferry but intend to fly back to belfast. I do not have a passport but do have a Northern Ireland electoral I.D. card - will this suffice as a means of I.D. at the airport.
Fly or ferry.
Not officially, but you may be asked for ID by Irish immigration officials.
By plane or ferry.
Yes. I've never been asked for any form of ID travelling from NI to Scotland by ship. Its generally regarded as a domestic ferry trip. But if you are flying you need to check with your airline as to what form of ID they require. Ryanair etc require a passport for all of their passengers
