I think those were the only states issuing documents of that type. All the states issued documents declaring secession, but really did not allude to causes like these four.
There were four states that seceded after the start of the war, citing Lincoln's actions as cause. These states were a mixed bag of Unionists, Democrats, etc. Arkansas was putting off it's vote until they declared a special session after April 12, the start of the war. Virginia also declared secession shortly after this date.
A state like North Carolina was really caught in the middle. It would have been difficult for them to side with Unionists when Virginia seceded because they would have been geographically cut off. Lincoln also declared soldiers as treasonous in places like Kentucky, a state that tried to stay neutral. Lincoln's aggressive action forced the hand of a lot of people who were more ambivalent.
Anyway, not to sound overly academic or something, but just pointing out that some states took action, in large part, because of an aggressive Lincoln who greedily would not let the South go and escalated with violence.
