This is a tricky question. In Sumeria they believed heavily in Polytheism which held far more than 7 deities. In fact, by Ur's 3rd Dynasty there was over 3600 documented dieties. To start, Anu (An) was the "king of gods" much like Zeus or Odin respectively. He was god of the skies and the heavens. His wife was Ki, goddess of the earth and life.
Together Anu and Ki parented the Anunnaki. These were children/gods who served also as the judges of the underworld. They were;
1. Enki: God of the rivers and lakes, knowledge, and of male fertility.
2. Enlil: God of the air.
3. Inanna: Goddess of anger (war/anti-peace), lust, and female fertility.
4. Nanna: God of the moon and lunar cycles.
5. Ningal: Wife to Nanna
6. Ninlil: Enlil's wife and goddess of the winds.
7. Ninurta: God of wars and agriculture.
Each of the Anunnaki were openly worshipped as Gods. Worship involved sacrifices meant to please or appease each god and grant a favorable outcome to the worshipper.
