The top one is an inkcap, possibly Parasola plicatilis but could be something else. Seeing it at a younger stage would help, and to check the cap and stem with a hand lens for hairs.
I wouldn’t like to comment on the other two. You need better close ups with larger images to make a guess. The last one is a good example of where a knife would be useful, to dig up the whole mushroom. Not only do you keep the stem intact, but sometimes important features can be below ground (eg a bulb or coloured mycelium)
Some info. is needed sometimes to even get to a Genus (including substrate & ecosystem). Spore colour is a minimum requirement as immature gills of even dark spored species can be white. Having said that the top collection is a Parasola, but to go further you need details of spore size.
The second one seems to have purple-black spores and a glutinous/gelatinous cap?: might be a Stropharia (or even a Psathyrella?)
The last one may be a Agrocybe (which have snuff-brown spores). It seems to have the remains of a ring on the stipe and also on the cap margin (A. praecox?).
