I think you can use a night owl, or a night-person.
I think a sleepless man is fine. Another similar word is an insomniac (a person who suffers from insomnia), but I believe that you know it already.
Actually, what you describe sounds pretty much like me myself. :)
Sometimes, people called me a vampire, a batman, or a dark knight, which is not quite to my taste. In casual chatting, I personally prefer a night dweller or a man of the night more.
Here is an excerpt from Wikipedia's page Night owl:
A night owl or evening person is a person who tends to stay up until late at night. The opposite of a night owl is an early bird, a lark as opposed to owl, someone who tends to begin sleeping at a time that is considered early and also wakes early.
The usual term when I was in school was scratch paper—scraps of paper you "scratch out" calculations and notes on, to be discarded after results have been fair-copied into your exam answer or essay.
- Laure calls my attention to scrap paper, which appears from this GoogleNGram almost always to have been more popular in BrE, and to have become more popular in AmE since I left high school.
- Jim calls my attention to the alternative term work sheet. This works, too; but in my experience it is usually employed when you are supposed to turn in the paper, with your exam, rather than discarding it.
A working paper is usually either a) a report on a "work-in-progress" or b) a "working" version of a paper which is still in development and not yet ready for submission or publication.
The traditional term in textual criticism for an author's manuscript draft, often full of strikethroughs, insertions and corrections, is foul papers, from which a "clean" version or fair copy is made.

It depends on the exact context, but I would probably call them "bad/poor communicators", though something more tactful would be required if I had to say this to their face. The polite method would be to emphasise that someone else was a "better communicator", or "better at public speaking".
