@180.73.50.118: A 'E-3 stamp' is more restrictive than a 'E-4 stamp', since a 'E-3 stamp' means the ship cannot participate in E-4 and E-5, whereas a 'E-4 stamp' just restricts the ship from E-5; I would imagine that if a ship with a 'E-4 stamp' sorties back to E-3, that ship's 'E-4 stamp' would be replaced/overridden by the 'E-3 stamp'.

However, I would not expect the opposite to happen (i.e., I do not think that it would be possible to replace a ship's 'E-3 stamp' with a 'E-4 stamp' by sortieing that ship into E-4 easy mode), because that would create an easy workaround for the E-4 ship locking (so if this loophole was possible, we would be able to use all of our E-3 stamped ships by first sortieing them into E-4 easy, giving them E-4 stamps, and then re-sortieing the same ships into E-4 on medium or hard).

Finally, E-5 does not stamp ships because E-6 does not have ship locking.
