There is nothing special to do.
Just give a different home for each one.

If I were you, I wouldn't worry about the TNS names configuration yet. Get your 8i snd 9i Oracle Homes installed and the two databases created: once that is done, you'll be in a better position to understand the netwrking.

And by the way, you said Quote:

how can we manage exp command to backup database

Never forget that an export is NOT a backup.

As far as, Windows is concerned, if you are going to work on different Oracle Homes then you need to set them manually before invoking the utility.

Use the command:
set ORACLE_HOME=path of the Oracle Home
set PATH=%PATH%;%ORACLE_HOME%\bin

If you don't want to bother with SQL*Net setting use the following:

set ORACLE_HOME=<8i home>
set PATH=%ORACLE_HOME%\bin;%PATH%
set ORACLE_SID=<8i SID>
exp ...
set ORACLE_HOME=<9i home>
set PATH=%ORACLE_HOME%\bin;%PATH%
set ORACLE_SID=<9i SID>
exp ...
