Which file I need to modify for the changes to take effect after a restart..

For a specific user I can put in .profile file in the home directory.

But I need to modify it universally, hence all the users will get impact with the settings.

For bash:

When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable.

So you can add your modifications in /etc/profile and this will affect all users.

Note you don't want to modify all of these, some are user specific.

The most important one is OSTYPE, you should set it to HP-UX. ;-)

>But I found only the few things there in /etc/profile.

That's the way it should be, few as possible.
The others are set based on the user's .profile in their home directory.

>But how can I set the timezone, since I dont found any entry for timezone in /etc/profile
TZ=Asia/Calcutta

The same as the others:
TZ="Asia/Calcutta"; export TZ
