Unique Visitor is "a person". We use the terms "Unique Visitor", "Visit" and "Page Views" in their normal english-language meanings, much as if they were people visiting your house.
There are some technical caveats to this: we track people with a cookie in their browser, if you delete it you will be viewed as a different visitor, same thing if you use a different browser.
Robots that impersonate humans may also be counted as unique visitors.
New visit is a visit from someone who's never been to the site before,
Returning visits are visits from people who have visited before:
If I come to the website, do some stuff, and come back the next day you will get

Returning visits (people who have been to the site before)
1 Unique Visitor - me
2 Visits (one for each day I visited). The one from the first day is a "New Visit" the second day (and all other visits I ever make) is a "Returning Visit"
x page views (one for each time I loaded and viewed a page in that visit)
