How to update them all?
FreeBSD, BSD and macOS is not the same.

The updates for macOS system utilities come from Apple and are included in both major and minor system upgrades for macOS that you install using the App Store.

There's no need to update these utilities through other means.

If you want other programs than the Apple-supplied ones, you can install for example Homebrew that allows you to install alternatives. Keep in mind though that even though two utilities might have the same name across different operating systems, they are not necessarily the same program. That is "tar" is not the same on FreeBSD as on macOS as on Linux (etc).
