Question: who are all the titans?
Answer: According to Hesiod's Theogony, there were 12 original Titans: the brothers Oceanus, Coeus, Crius, Hyperion, Iapetus, and Cronus and the sisters Thea, Rhea, Themis, Mnemosyne, Phoebe, and Tethys. At the instigation of Gaea the Titans rebelled against their father, who had shut them up in the underworld (Tartarus).
