Hi Nadine First photo is certainly a Coprinus, very probably a Shaggy Ink Cap. Cant make other two out, its almost impossible to identify fungi from pics, one needs at least some idea of size and the what they are growing on.
The Coprinus are ink caps and as they age the cap deteriorates into a black inky mass, they are edible when young, but I find they need a lot of garlic etc to make them really tasty.
Yours PeterK
