That's a boat load of questions!
An executable is the actual program file of machine instructions which
you run.
I'd guess Windows has the same - think of .exe files!

Regarding Gentoo, it does indeed recompile system executables every time
they are installed,
The thinking being you get best performance when they are optimised for
your exact architectire.
Me, I say if you want to run a code like Openfoam or other scientific
application stick to a mainstream distribution.
Like Redhat Enterprise, Fedora, SuSE (Enterprise or OpenSUSE).
I may be wrong, as I am not a Gentoo weenie.
