I attempted to remove a few tree stakes which, by rights, should have been removed a couple of years ago.

The all broke at ground level so the stump of each stake has been left in the ground.

I attempted to lift one but couldn't and ended up damaging the bark.

Will the stumps remaining in situ impair the trees in any way?

No, they should be fine.
Just cover with a skim of soil.
