All of your grandmother's grandchildren are your first cousins or your siblings or you. Her great grandchildren are all your first cousins once removed, except those who are your nieces and nephews, or your own children.
In general, first cousins share a grandparent. Second cousins share a great grandparent, and so on. Work out the level by counting the words grand and great. So great-great-great-grandchild is level 4.
