ARC has had a long history - as a startup in 90's. There used to be ARCTanget Instruction set (and cores A4,A5... based on that) which 10 years ago got deprecated by current ARCompact ISA (600 / 700 cores). So yes it is a family of architectures - but all we care about is the ARCompact and 600/700 at Synopsys.
However, I don't think there were sub-architectures or forks which floated around. The MIPS "ARC" seems to be some sort of firmware standard, but not related to ARC: Ralf would you care to shed some light ? I don't know of any ARC arch other than these.

As of now yes, but in near future we may have a new Instruction Set and cores based on that - so it will be better if we keep a non specific name.
