I agree with sweet Betsy, either Kousa dogwood (will bloom after leaves emerge) or native flowering dogwood which will bloom before leaves emerge. The fruit differs also. Those are the flower buds at the branch tips.

Is the third photo a true shrub or stump sprouts? It looks rather birch-like to me but it's too out of focus to see the tooth detail. Where are these plants growing?

Number 3 is shrub size. Western Indiana. 5a. Thank you!

May I suggest Hamamelis for no.3?

I don't think the third one is witch hazel/Hamamelis. Neither the leaves nor the buds looks right to me. The leaves don't look like native hazel/Corylus, though the buds are possible.

No definitely not a true hazel. I thought I could see some swollen buds going to be a winter bloomer.

Perhaps a Viburnum for #3.

More like Winter Hazel (Corylopsis pauciflora) for #3.

The prominence of the flower buds in #1 & #2 suggest Cornus florida over C. kousa.
