Yes these are all RS kilts. Which other battalion other than the 9th wore kilts?

Yes, the Hunting Stewart is asymmetric but that is not why it cannot be turned 90 degrees and used for kilting. The same would apply to any tartan because turning it thus would mean joining sections of material and would also mean the loss of the selvedge.
Either the fabric is used back to front in some instances pictured here or the fabric has been woven at 90 degrees to the other setts.
