First... for Boost Build related problems - the boost.build list
might be a better choice.

Seems doable. :-)

I can not directly help you with the doxygen part as I never actually
used it but there is a doxygen toolset that should be able to do what
you want. Grep under the boost libs folder for Boost library Jamfiles
using this toolset for examples.
Any way... do the following:
1. Prepare a top level Jamroot file in the Project-root folder.
2. Prepare a Jamfile in 'doc', 'src', 'examples' and 'testcaseX' folders.
3. Make 'testcaseX' Jamfile build the corresponding test project.
4. Make the 'examples' Jamfile list its testcaseX projects using the
build-project rule. You can possibly use the glob rule here so you do
not need to specify each testcaseX folder.
5. Make the 'doc' Jamfile build the doxygen documentation (which I
can not help with :-)).
6. Make the 'src' Jamfile build the main program.
7. Make the Jamroot file define the top level project, specify its
source-location as src and call build-project on 'doc', 'src' &

Now myExecutable will only get build if you explicitly request it on
the command line or some other build target explicitly lists it as one
of its sources.
I am not sure at the moment whether explicit works with sub-project
targets or whether you need to use the use-project rule instead of
build-project in order not to have them build by default, by that should
be easy to test.

You can place the Jamfiles wherever you like. :-) You can point your
project to where its sources are by specifying its source-location
(possibly multiple ones) in its project rule call. Then all (well
actually most... it makes more sense to search for some stuff from the
Jamfile anyway) file and folder names you list will be searched for from
that location instead of from the Jamfile's location.
[Note though that paths used in <include> properties are always
searched from the Jamfile's location. I remember some discussions a long
time ago about changing it to work based on the source-location as well,
but nothing seems to have been done.]
You make bjam process your Jamfiles in any of the following ways:
1. Go to its folder and run bjam.
2. Go to one of its parent project's folders and run bjam <projectId>
or bjam <pathToProject> (not sure about this).
3. Make some other project build it using the build-project rule.
4. Make some other project reference it using the use-project rule
and then have its targets available.
Hope this helps.
