I think the top 3 might be Taiwan, not sure about the others.
There are no pix of currency at your link. At least not for me. Just a bunch of random pix and vids in an annoying collage.
Which was probably not your intent.
Well, that’s discouraging. Will try to see what happened.
I think the two black ones might be Korean.
They are China, China, Taiwan, Japan, Japan. All recognized by Google Lens.
Worked fine a second time. I have no idea what else I might’ve clicked. Sorry to confuse matters.
The two black ones on the bottom are Japanese.
The two on the top are five yuan notes.
The one on the left above the Japanese 10 yen note is a Republic of China note.
The Chinese notes seem to be from before the Republic of China government fled to Taiwan.
China 5 Yuan 1936 series
China 5 Yuan 1940
Taiwan 10 Yuan 1960s
Japan 10 Yen 1940s
Japan 1 Yen 1940s
Thanks, all.
May I point out an interesting nuance here?
I believe those top two bills are pre-Chinese-civil-war money, from when Taiwan was still China. They’re from before that particular government (the Republic of China) fled to the island of Taiwan. At the time those bills were issued, that government still ruled over the mainland, or what we now call “China”.
- The top green one was issued by the “Central Bank”
- The second blue one says “Bank of China” (because Taiwan was still China then)
- It’s not until the third red one (post civil war) does it say “Republic of China” (the alternate/official name for Taiwan after that government retreated to the island and their opponent, the People’s Republic of China, took over the mainland)
I believe all three bills depict Sun Yat-sen, the first (provisional) president of the government of the Republic of China, back when it was still China. He’s still recognized as a historical figure in Taiwan.
Those bills are still acknowledged in the Taiwan central bank’s history. They are similar to 中央銀行 券幣數位博物館 and 中央銀行 券幣數位博物館 (though not necessarily the exact same period or denomination). EDIT: Despite the Chinese names in the linked page titles, the actual pages and histories are in English.
So as to whether those bills are Chinese or Taiwanese, I believe the answer is “yes” 
Or, what @Monty already said… sorry I missed that.
@Reply No worries. I missed the one from after the ROC relocation to Taiwan.
I was curious about the yen notes because the 1940s covers vastly different circumstances in Japan.
I found a cite which puts the one-yen note as a 1943 series, and which also notes that they were no longer printing serial numbers sometime in 1944 because the economy had gone to hell with the war not doing well for them at that point.
