It's surprisingly easy to obtain those two items. diphenylamine is used as a treatment to prevent apple rot, banned in Europe but still available in North America from two companies. I checked a bunch of SDS and it's just DPA mixed with a solvent and stabilizer.
Aresnic is a bit more tricky and I don't really know of any ways to easily get arsenious oxide. I did however find quite a few arsenic ores and minerals for sale on ebay. Making the oxide is easy you just have to combust arsenic.
A hydrogen cyanide concentration of 100ā200 ppm in breathing air will kill a human within 10 to 60 minutes. A hydrogen cyanide concentration of 2000 ppm (about 2380 mg/m3) will kill a human in about one minute. The toxic effect is caused by the action of the cyanide ion, which halts cellular respiration. It acts as a non-competitive inhibitor for an enzyme in mitochondria called cytochrome c oxidase. As such, hydrogen cyanide is commonly listed among chemical weapons as a blood agent.

Back when Alfhabay (with a p, fuck the fillter) was still a DNM I saw a German vendor selling potassium cyanide, the product image was just a skull and crossbones on a black background. He had all five star ratings and the only review left said "Works as intended".

It's actually a very painful and agonizing death. You're basically asphyxiating yourself. You die within a minute or two, but that minute or two is going to be very agonizing.
