The Amateur Mycologist is here again.
First does look like an Amanita Muscaria, or Fly Agaric, getting on in age. I would hesitate to call this mushroom deadly though - it is not the Destroying Angel or the Amanita phalloides - it should not have the powerful mytotoxin which destroys your liver. However, it is poisonous and, historically, considered vaguely psychotropic. The experience, based on recountings from the internet, sounds less than ideal.
To be blunt though, don't eat it. That's my policy on all finds.
The Ids get more difficult using just one photo as we go down. The second one looks vaguely lobster mushroomy. This usually means a Russela genus taken over by a fungus eating mold that actually makes the whole thing delicious. But again, from one photo, can't be sure.
Three and Four appear to be Pleurotus ostreatus or a related species - browned from sun exposure, growing with long, decurrent gills and in groups - and from what I can see off wood. You would need to do more to identify them for sure.
Five and six might be in the Armallaria genus - but much more information is needed to be sure.
