Yes. All authors who claim copyright in a source file should be
credited in the Debian copyright file, together with the exact
statement of license they issued.
For many free licences this is a legal requirement, because the
notices in the source are not shipped in the .deb otherwise, and
even when it isn't it would be discourteous in extreme not to
quote it anyway. This is what /usr/share/doc/*/copyright is _for_.

Current best practice is, as far as I'm aware, something like:
1. Minor formatting differences, including different styles of comment
markup, line wrapping and other whitespace, can be compressed away
in the copyright file.
2. Similarly, two authors who assert copyright but give identical
license notices can be compressed into just giving both copyright
assertions in the copyright file, followed by the common license
3. Actual differences in wording should be preserved, even if they may
seem insignificant to the packager, except perhaps where the
difference is beyond any conceivable doubt due to a mere typo.

Policy section 12.5. A "verbatim copy of its copyright and
distribution license" means just what it says. Policy perhaps neglects
to explicitly point out that this applies simultaneously to every
copyright [notice] and every distribution licence that covers the
package, but I still think this can safely be left to the reader's

Yes. See e.g. /usr/share/doc/xlibs/copyright for an example of how
large this can be in complex cases, but it all has to be there.

Yes, it looks like a minor rewording of the common 3-clause BSD license:
