Can anyone identify these sacred items? Also if possible from when and where?

Well, you have the look. Indonesians originally came through the mainland, so who knows. It is said they are related to the original peoples of Taiwan though, a long way away from where you are. But maybe your ancestors came from further northeast too.

 

I just know the oral story of migration. For our tribe it's wui supun>iipyo supun>nyime supun>miido supun>siilo supun (order being past to present). Supun/Supung is a general term denoting land/place/world. "Siilo supun" means the present land, which is my home town/village "Ziro", and "Nyime" I read and deduct is Tibet (also note there are varying versions in some Miido comes just before Nyime), rest I have no idea of . The migration narration does imply the ancestors are from north, but can't be totally sure of it. There are some daily use words in our language which links us to Austroasiatic language group, no idea about Austronesian though. Basically everything about our past is making the best guess you have.

 

Blueblade, I found this, check out the photo on page 2, it bears some resemblance to the disc on the second item you posted:

I think if you delve into pre-Buddhist Tibetan amulets, you could come even closer.

This right?

It does bear some resemblance. The only thing is these Thogchags are supposed to be amulet of some sort, while Ranuh Akhii doesn't seem like an amulet. Its upper design could have been inspired from similar origin though. What I noticed in the Akhii(means comb in Apatani), is that it has a three-pronged pattern. Maybe that gives us some sort of hint to something?

Also after some reading in the site you provided and with inspection with one of my friends, made me wonder if the first picture could be some sort of Khakkhara or a prayer wheel? What do you think?

 

Anyone with any more lead on this?

 

You won't know what they are unless you can see them in person, hold them in hand, test what they are made of, examine construction, etc. A quick google found silver head dress pins by the Meow (Miao) People, could be something like this but without size, material, provenance to the extent possible (where and how was it come by) it will be pure guesswork.
"The Miao live primarily in southern China’s mountains and some have migrated out of China into Southeast Asia Burma (Myanmar), northern Vietnam, Laos and Thailand."

Sadly, it does seem that way. Guess I'll have to live with the mystery, at least for now. Hopefully some day I'll be able to inspect it myself. But thanks for the contribution, I'll be taking everything from this forum into account.

 

Guys, I think I might be getting close to the first object. It seems to be related to a European folk instrument. Its common name is Bladder Fiddle or Devil's Stick, but it has lot of other names depending on culture and region.

It's also sold in live auction sometimes: https://www.liveauctioneers.com/item/75866498_folk-art-carved-wood-devil-top-stick-jingling-johnny










It can be played this way:





They all might look different in detail but I think we can see the general pattern. Jingles on top, drum somewhere in middle and then a string or some other additional items. This could explain the circular thing the item has in the middle and also the broken string/strings.

I still have no idea where, how, or when our tribe got it but I think we can make a better guess now. It's highly possible Zhangzhung culture could've played a part, considering there is also tentative evidence of it having Iron age technology. If that is true then the mystery of rest of the remaining items could become easier to solve.
