No, the Spartans didn't pray to another god because, we should remember they were in different city and state. Also all ancient Greek were isolated so I think they didn't pray to the same god.
Yes they all believed in the same gods and goddesses.
yes
They shared the Greek language, religion, history and customs.
wrong same
Both cities worshipped the same basic gods and goddesses, but their importance varied. For example, Athena was the goddess of culture, art, music, poetry, and all things creative which were frowned upon in Sparta. Athena was also the patron goddess and protectress of Athens, the city being named for her, and Athens was the only significant rival to Sparta. Of course, she would not have been a favorite goddess in Sparta. Yet, she was a goddess, and it was unwise to disrespect her. Also, Athena was a warrior. Of the major Hellenistic female goddesses, she was the only one depicted with armor and weapons. At least this aspect of Athena's personality may have been admired by the Spartans, or maybe not.
Sparta and Athens had many differences and similarities in their government. Only a few Greek city-states had kings. Sparta had two kings, usually cousins or brothers. One would stay home and the other would go off to fight wars. Athens created the first democratic system and many other city-states copied them. Athenian democracy did not give power to everyone. Most of the people in Athens couldn't vote, including women, slaves, foreigners, and children.
You are obviously asking about ancient Athens. Well, during the years there were different allies to Athens according to what the needs required. At some point it could have been Sparta and then at another they were one against the other. Anyway, Sparta was mostly allied to Athens when it comes to matters of being commonlt threaten. Thebes and Megara were also traditional allies on account of being close to Athens. Boetians and Corinthians too for the same reason.
