@rainbow and @sableguy : Totally amazing finds, I never would have dreamed of the possibility to identify all of those super niche items. You do the community and me a huge favor! 
Regarding Item 37 (Starmie pacth) @rainbow: I am very curious why the loops are different. If they had been part of a kit, they surely would be the same, wouldn’t they? Nevertheless, you are right; they seem as if they were put together by hand, as indicated by the different orientation of the white patch on the back. What strikes me is the following: Why would they need a patch and a loop? It would be reasonable to assume they served one specific purpose. 
Regarding the Pokemon Town full color collection 3, @rainbow, you are right, I have it not in my collection, but I surely will add it later on next year. Thank your for the hint. I hope, I will find one with the housing and the intact capsule.
Regarding the Pokemon Full Color Stadium Part 8, @rainbow, same as above, will add this one later. Thank you again for the hint.
Regarding 262p, Special Moves Pokémon Kids 8 (2008), @rainbow, I will take photos as soon as this one arrives, as I understand the Japanese text, the seller claims, it was a special transparent edition, but sun exposure or factory error seems more likely if there is no information out there you know of.
Regarding 104, D.Mangas hors-série n°36 - Juin 2000, @sableguy, I would never have dreamed, this card would be identified. I was browsing google one day and the picture search showed this one. I clicked it thinking the link would surely be dead. I ended on a Frech website and ordered it, still thinking it would never arrive. And here we go, a french hand cuttable card identified and encapsulated! WOW! 
I will add the following data to the OP:
104: 06-2000: D.Mangas – Special Edition No. 36 (French hand cuttable card, Starmie)
223: ??-1997 – Nagatanien Pokemon Furikake Mini Model (Starmie)
252p: ??-1997(?) – Pocket Monsters Full Color Collection Part 10 (Starmie figure)
262p: ??-2008 – Special Moves Pokémon Kids 8 (Starmie figure) 
transparency maybe caused by sun exposure or factory error
Thank you!! (PS: I added one more item in the OP 
)
Best,
