Don't use < > 's. Double quotes are fine, and are needed if the VM has a space in the name. The VM names are case-sensitive, too.

Good question, I personally don't know this one.

This one I'll guess about. They might be major and minor version numbers, like Virtualbox's "6.1" is the major number and ".36" is the minor number.

I don't think they mean anything, merely that numbers can go there.
Please note the warning in the manual that numbers may need special treatment to get recognized.

No. Run them wherever vboxmanage will work. The "VM name" will run the command on the correct VM.
