How do I determine the current runtime client version on an AIX box?

Run 'db2level' from within the client instance environment.

What are the steps for upgrading a DB2 Client on an AIX box from 7 to
8 (or 9)?

See the version 8 (or 9) documentation.

- do I need to uninstall 7 or just install 8 overtop of 7?

See the version 8 (or 9) documentation. (You can't do that. The docs go
into much more detail about how to migrate.)

See the version 8 (or 9) documentation. (Client / server fix levels don't
need to match.)

do I choose the level of the latest server?

Choose the latest level possible that still talks to all your servers. To
find that out, see the version 8 (or 9) documentation. (Version 9 clients
won't talk to version 7 servers.)

- would it be wise to install 9.x runtime client to talk to 7 and 8

See the version 8 (or 9) documentation. (No, not wise at all, as you won't
be able to talk to the version 7 server(s). Mind you, having version 7 at
this point where version 8 is about to go out of service seems unwise as
well. And you can't migrate straight from version 7 to version 9 - you have
to go through version 8.)
