I think the first one is Marasmius oreades (the clay coloured well spaced gills pale buff cap and tough stem are the characters I am using)
Middle one - not sure
The last on is a species of what used to be called Collybia. These have tough often flattened stems, perhaps someone else will be able to confirm the species. and perhaps the current Genus.
