Welcome to the forum Surgi.
ALL of your keris would ideally have "loose" handles and yes, your should be able to easily remove both the hilt and the hilt ring from your keris. The hilt is generally held in place with a bit of cloth (or string or even sometimes hair) wrapped around the tang (pesi) to form a pressure fit. The hilt should be held firmly in place, bit if there is too much unnecessary play in the the hilt you can tighten it up by wrapping a bit more cloth around the pesi.
Here is a link that should help you with posting photos. If you have any difficulty after reading it be sure to let us know.
