You are correct about the 5th Amendment. Under Barron v. Mayor of Baltimore, the 5th Amendment was only a restriction against the Federal government and not the states. So I did a quick and dirty review of some of the state constitutions of the Confederate states to see what individual rights they protected.
South Carolina, North Carolina, Tennessee recognized rights of life, liberty and property (sometimes mingled with the rights of Article 39 of the Magna Carta), but only as applied to “Freedmen.”
Georgia did not have a provision similar to the 5th Amendment, but did restrict the right to plead cases to freedmen.
Virginias constitution of 1830 recognized very few rights but made no mention of freedmen. It did limit suffrage to white males.
Alabama and Mississippi recognized rights of life, liberty and property but did not restrict them to freedmen.
Georgia and Mississippi prohibited the legislature from passing any statute abolishing slavery or freeing slaves without the consent of their owners, but none of the other states specifically mentioned slavery or protected it, except as to their mentions of freedmen.
So for the slave owning states that would later secede, there was really no consensus as to the status of slavery from the standpoint of enshrinement in state constitutions.
As for the incorporation of rights in the Bill of Rights against the states, we may have to have that discussion another day.
OK. The incorporation of rights in the Bill of Rights against the states isn’t relevant here anyway. It doesn’t arise as an issue until the 14th Amendment upon which the flawed doctrine uses as its basis.
