Twin means it's two single beds. I doubt you would actually FIT two people on one of them! - and the rail company would refuse to book three into a two-berth compartment. Sorry but one of you will have to be by herself in a single or sharing with a stranger :(
Because of the small size of the country, these are only available from London to Scotland and London to Cornwall, so I'd think of doing it some other way to keep together. To Devon and Cornwall, there really isn't much alternative except the train, though it's possible to fly to Plymouth, but to Scotland you could fly at least as far as Edinburgh or Glasgow. Look up easyJet for cheap air fares to Scotland.
The sleeper trains in the UK all have single-berth bunks. In days gone by sleepers ran across country with many stops but these days they only run from London to Scotland or London to Penzance.
The First class sleeper compartments have one single bed, the Standard class sleeper compartments have two beds, one above the other.
You would not be allowed to have someone sleeping on the floor or sharing a bunk for safety reasons. They are wide enough to be comfortable for one normal size person but two bodies would not fit - as soon as the train passed over its first set of points someone would be thrown out of bed!
There are no "double beds" and no compartments for more than two people. When you buy your ticket you will be allocated your reserved compartment and upper or lower bunk. You can't save money by cheating.
Some trains also have seats that you can sleep in. These are cheaper than the compartment or "cabins" with beds.
The trains are comfortable and tend to ride fairly well. Because the passengers are asleep and don't expect to arrive much before breakfast they run slower than ordinary "day" passenger trains.
It is good to get to bed in London and then wake up for a cup of tea and a good breakfast, to see the Scottish Highlands passing the window (unless it's foggy).
Look at the train operators' sites for more information:

There would be no point doing this, and in any case only two very thin people could fit in a bed on a sleeper - they are quite small beds.
Only someone with a sleeper berth ticket is allowed into the sleeping coaches. (Sleeper trains also have some coaches with ordinary seats, but passengers with a ticket for a seat are not allowed into the sleeper coaches). In theory I suppose someone with a sleeper ticket (and therefore a bed of their own) could try to squeeze into someone else's bed instead of sleeping in their own one.
If its a twin berth, with only 2 beds, then only 2 people can sleep in that cabin.
Beds in sleeper trains are generally singles and tiny; you'd struggle to get an extra person in one.
No, you need to book three tickets!
The Standard Sleeper Berth (Twin) provides accommodation for up to two people. The Twin Berth is ideal if you are travelling with someone or if you’re happy to share. Couples are permitted to book together but if you book on your own you may have to share with someone of the same sex.

Seriously? Of course they're not going to let one person travel for free. Use some common sense.
Night trains here in UK usually make long stops enroute - distances are not like they are in the USA - a day train can easily race from London (Paddington) to Penzance (Cornwall) in about five or so hours.

As Gerd says. I don't really see the point of sleeper trains as all journeys in Britain are short enough to complete them within the daylight hours of one day. Daytime trains are also faster and very frequent and you will see a lot of the country as you travel. Buy a Britrail Pass before arrival

FFS. It's 'allowed' not 'aloud'. Check what you have written before posting.
And it's one bed, one person.
Not places you need to worry about - just the temperature
