Public domain, for more than a century. What could still be protected is a modern arrangement.
Both the song and music are so old that copyright law does not cover them.
Copyright law varies from country to country; in the USA, any song published before 1922 is in the public domain. Mostly, the copyright survives until the composer(s) die and then for 75 years afterwards.
No; copyright is administered by St. Nicholas Music.
"We'll Meet Again" by Vera Lynn was first released in 1939, which means it would have entered the public domain in 1995, following the standard copyright term of 56 years at the time. However, the Copyright Term Extension Act of 1998 extended copyright protections for works published between 1923 and 1977 to 95 years, placing "We'll Meet Again" under copyright protection until at least 2034. Therefore, as of now, the song is not in the public domain.
No, but a new work based on a PD song can be protected by copyright. A new translation, setting, arrangement, etc may be copyrightable. A common example would be the traditional Shaker song "Simple Gifts," which is in the public domain, and Aaron Copland's popular orchestral setting "Variations on a Shaker Melody," which is protected by copyright.

No one. It's in the public domain.
Works no longer protected by copyright are said to be in the public domain.
Pubic domain occurs naturally when a copyright expires. In theory, a copyright owner can intentionally disclaim any power to enforce a copyright, making it as if it were "public domain".
Nobody. It's public domain.
Neither Copyright nor Patent law protect domain names.
