I'd say maybe black oak? It's in the red oak family. And young or shade leaves can vary a good bit on oaks. Twig iD would be best if it can't be determined. I was never good at twig ID in school and never really learned that. I could ID well enough from leaves and bark to not need to go that far.
X2 red oak family. Bristles on the leaf tips are a dead giveaway. IME the leaf shape at that age is atypical for any particular oak variety, making exact identification difficult.
I think this is some type of holly. The way the leaves attach is not like any oak that I know of. And holly can either be an evergreen or a deciduous tree. Holly was at one time thought to be in the oak family(a long time ago...).
