Here are the answers to the questions given above:

1. Use a Git alias, a shell alias, or a shell function.
2. You can use the git config --get-regexp ^alias\. command.
3. Use git difftool for displaying differences, or git mergetool to help with resolving merge conflicts. There is built-in support for many of the existing graphical tools.
4. If it is about configuration values, you can use git config --show-origin (or --show-scope). If it is about per-file attributes, use git check-attr. If it is about ignoring files, use git check-ignore.
5. Use the pre-commit hook (and other similar hooks) to warn if best practices are not being followed. There are many third-party tools that help with hook management and often support various helper tools such as linters and code formatting tools.
