Yes, it is possible that the poles of Earth were changed and it has taken place many times. The reason behind this is the magnetic moment of the rocks that make up the ocean floor having an alternating direction. The direction in which they will exhibit depends up on which way the poles were oriented when the rocks were being formed at the mid-ocean ridge.
Yes, in fact they do change every so often (although every so often is a huge amount of time).
