Any package that is a shared with ubuntu and a supported ubuntu package
(ie not universe or multiverse) will receive updates until 2017. This
includes kernel, Firefox, etc.

The Xubuntu specific packages no longer receives updates

yes, you can use it for as long as you like. The longer you use it the
more out of date the unsupported packages will be

I do not know the status of the Xubuntu packages that are no longer
receiving support. In general, ideally when something goes out of support
it has at that point been patched for all known CVEs, and over time
new CVEs maybe discovered but the package will not be patched (because
it is no longer supported). So over time known vulnerabilities against
the package will accumulate.

No. I am saying the packages that Xubuntu shares with Ubuntu will receive
security updates. Xubuntu has several packages that are not shared and will
not receive updates.
