No. If you build a jail, only the base system, without the third party
software you built and installed on the host system will be the jail.
You have to build you these application in the jail.

What do you mean with "new things". A jail is a "virtual" system and has
nothing to do with the host system the jail is running on. If you want
to install new software for/in a jail, you have to login to that one,
and start to build that particular software you want to run.

No i dont think so.

Normally no. Or, i dont heard that in past happend (but it maybe can
happen in the future).
A jail is secure, but you as the Administrator has to watch out to
secure the jail as any other system you administrate.
Please, read the very very good manpage of jail --> man jail.
