The first is Catoptria falsella (Chequered Grass-moth).
The second is Agriphila geniculea (Chevron Grass-moth).
The third is difficult in the absence of size. If the right size, I cannot really see past Large Yellow Underwing.
I recommend buying some pots so that you can pot them up & look at the features. You will learn a great deal more and enable yourself to take photos. Side on pics normally show features best and match illustrations for grass pyralids & obviously most macros are photographed from above. Popping a moth in the fridge will cool them down & they can be photographed & released unharmed. Plenty of options out there:-
Clear Plastic Containers with a screw fit lid. Please note all round containers are for holding insects (and other small items) not for photography - You will need flat containers for that, due to the manufacturing processes involved to bend plastic.

I also recommend a cheap hand lens to look at the moths in more detail:-
All the best
