The Linux kernel offers the user a host of operating systems that are free and can be copied and distributed as much as you like. Known genetically as 'Open Source' and, often small group or community maintained, you can freely try out a variety of distributions. All this without having to register to get a licence as you would need to do if using propriety MS Windows.

Linux, Minix, Coherent, FreeBSD, etc. These are all clones of Unix
No, Linux IS Unix, so the question makes no sense. Unix is a general term for a class of operating systems. Linux is also a term applied to more than one operating system variant, but all Linux OS are Unix OS. Redhat is one type of Linux. BSD is a type of Unix that is not Linux.
Linux is a Unix-like system. This means that it is inspired or influenced by Unix in some shape or form (Linux started off from Minix), but it is not directly derived from Unix. However, BSD is based on Unix, and macOS is indirectly Unix-based because of its mixed heritage with BSD.
