Vhdl codes for 8-bit ring counter

Thanks for your help so far.

The thing is the (edited codes) codes without the library imports compiled and had fewer errors but this then brings to mind a reply to this thread that stated ewer errors doesn't mean there are fewer errors with the code.

Please find below the errors, I hope this helps.
