This will set environment variables globally for all users
who login, not depending on the shell. There is also a user-level
file ~/.login_conf which overrides settings made in the global
file for a specific user upon login.

Don't touch this file! :-)

This applies for sh and zsh globally.

This is for the C shell.

This is the user-specific file for sh and zsh. It will override
any settings made in the global files. It will be read if the
shell is a login shell.

Similar for sh, csh and zsh, except .shrc and .zshrc will be
applied to interactive shells (which aren't neccessarily login
shells).

For bash: .bash_profile, -bash_login, and .bashrc.

This depends on how login shells and interactive shells are
being configured and how they inherit environmental variables.

Yes. Those informations can be found in the manual pages
of the respective shells ("man sh", "man csh", "man zsh",
and "man bash").
