The significance of the Emancipation Proclamation stated that "all slaves in those regions still in rebellion on that date would be free." This did not apply to border states or the regions under Union control, but to those under Confederate control. This was basically brought about from the strife between the union and confederate states.
The significance of Lincoln's ten percent plan was to allow Southern states to establish a legal government that would be recognized by the President as long as ten percent of the voters in a state took the oath to support the Constitution and the emancipation of slaves. The significance of the grandfather clause was to discourage voting among blacks and to basically stop them from voting.
The grandfather clause stated that all male persons whose fathers and grandfathers were qualified to vote on January 1, 1867 granted them the right to vote. This is contradictory because it was known that hardly any blacks were free back then.
The significance of the Fourteenth Amendment was to make blacks citizens of the United States. It gave them national citizenship and forbade states from depriving citizens of equal protection of the law; provided penalties for not granting black Americans the vote; excluded Confederates form holding office unless pardoned by Congress, and repudiated the Confederate war debt.
The significance of the "Forty acres and a mule" concept was to allow free blacks to establish themselves and to supply for their families. It was stated that once they were freed they would be given forty acres of land and a mule.
