#1 Dwarf Alberta Spruce
#2 Upright Yew
I'd leave the yew where it is. You're not going to find a bonsai in there. The spruce, I might pot it but would probably leave it too. At least it has some potential.
DAS, It'll be a hundred years before you get any branches under the first foot of trunk, and the existing branches won't have foliage within a foot of the trunk.
