The first frontier state to enter the Union was:

Tennessee
Vermont
Ohio
Kentucky
Louisiana

I believe it was Vermont

I am stuggling between Vermont, Tennessee and Kentucky

You can find that here:

The answer is still not clear.

There is a chart there with the dates when each of the states was brought into the Union. Check the states which you are not sure of. It will clarify.

It does not say which was first.
