Fungi are fun! That's a nice selection of mushrooms. That 4th photo looks like an Agaricus, with those pink gills. I made a YouTube video about ID'ing an Agaricus meadow mushroom that you might enjoy: Here it is
I'm looking forward to finding some boletes, with their pores instead of gills, now that our fall rains started last week here in Oregon's Willamette Valley. Happy mushroom hunting!
