Asking For Help Identifying 3 Evergreen Trees

[PGB1]

Hi All!
I've tried many sources to identify three trees I have and obtained mixed answers. If you all don't mind, can you help me figure out what species these are?

Tree A is about 2 feet tall and was given to us by a neighbor who said it was a "Norway Something".
Trees B and C are about 50 feet tall. I couldn't get a view of each separately since they are right next to each other.

Photos are below with close ups of the ends of the branches. On all three, the needles are soft to the touch, if that is helpful.

I sure do appreciate your help in figuring out what we have.

I also wonder if this (October) is an OK time to prune off dead branches from the large trees. I think it is not OK to do other trimming this close to winter. (But an mot positive.)

Thanks Again!
Paul

Tree 'A' does look like a Norwegian Spruce, commonly used as a Christmas tree.

Both 'B' and 'C' could be Piceas. Have a look through images on the web to see if they ring any bells.
