You can eat any of them, though some may kill you if you do :)
The first one is a morel, and the black one (also edible) is a black trumpet. Others may be edible, I'm not sure. The frog mushroom (Amanita muscaria) is supposed to be very poisonous, but there is an episode of Hamilton's Pharmacopoeia where he finds a man who eats them regularly. (This is not me suggesting you eat them yourself, just an interesting tid bit, mushrooms are weird)
You can eat fly agaric, but you have to boil it, change the water, and repeat a couple of times. The egg could be meant to represent a puffball, young stinkhorn (either of which people do eat) or an amanita still in the volva (v dangerous!). Tree nose looks like birch polypore. Purple could be based on amethyst deceiver. NSFW is stinkhorn. Deeply disconcerting is likely mealy tooth, though iirc there may be another one that looks similar. Citadel is possibly one of the yellow coral fungi (there's a lot).
