A little Identification Help Please

Basically this is at my Parents house, and most of these Tree's were planted then I believe, which is a good 10 years ago.
ive attached a few images of the trees, I think one is a green maple at the bottom? while one was broken in the wind and sent up a runner that is a red maple?

however the rest im unsure, particularly the other red leafed tree

overall my dad would like either a bush or tree to replace the dead one

where we live has no cover at all and can get very windy, as well as being on a hill so the soil isnt great! have you guys any recommendations of trees thay are hardy and readily available?

EDIT: Sorry Im having a little trouble with uploading my photos but I believe the other red coloured tree is a purple beech? It is an extremely deep purple colour and has the leaves of a beech tree, so it seems to fit!

the other green tree is a mystery and alas I now have no idea of what the dead tree's are to find out what doesn't work!
