Basic operation: tar multiple files into example.tar.gz
tar czf example.tar.gz file1 file2 file3 …

When untar multiple files, you cannot do this, it will fail
tar zxf file1 file2 file3
The reason please see this link, the solution is to use xargs instead:
ls *.tar.gz | xargs -i tar xzf {}
Or you can use find with -exec
find . -maxdepth 1 -name "*.tar.gz" -exec tar zxf '{}' \;

For example, if you want to tar things inside a folder but exclude some files
tar czf target.tar.gz ./* --exclude='createInstallerTar.sh' --exclude="target.tar.gz" --exclude='pushBIPayload.sh'
If you don’t exclude target.tar.gz, it will tar itself again.

List tar.gz file content, flag z is used to distinguish tar and tar.gz
tar ztvf target.tar.gz

If you don't specify target folder, untar will put things in current directory, use -C option to specify it. For example, I want to untar source.tar.gz file to /etc/yum.repos.d/ folder:
tar zxf /tmp/source.tar.gz -C /etc/yum.repos.d/

Sometimes I see people use -czf but sometimes czf, dash or not to pass flags?
Historical and compatible reason, no dash version is probably more portable.
tar is one of those ancient commands from the days when option syntax hadn't been standardized. Because all useful invocations of tar require specifying an operation before providing any file name, most tar implementations interpret their first argument as an option even if it doesn't begin with a -. Most current implementations accept a -.
