You can. If the dependency packages are compatible with the gcc you
are upgrading you can re-use them, or you will need to re-compile the
dependency packages themselves.

Replace? Whatever is installed on your system doesn't change unless
you uninstall the packages. You can have multiple versions of a
package installed in /usr/local, for example.

When building a gcc compiler, there are dependency packages. The
development/release cycle of these dependent packages is independent
of each other. So, not all releases will be able to produce a compiler
for you.
See Dan Kegel's matrix (for building cross-compilers), for example:
