Here are some ideas:
Goddess of life: Ha-Keres from Hathor, Egyptian goddess of love, art and music and Ceres, Roman goddess of plenty and fertility
Goddess of death: Ka-Phersis from Kali, Hindu goddess of death and Persephone, Greek goddess of the Underworld
Goddess of time: Nu-Hannon from Nut, Egyptian goddess of sky and Rhiannon, the Great Goddess of Celtic mythology, who in her three aspects - the Maiden, the Mother and the Crone - represents the flowing of time.
Names of the peoples: Keresians, Phersisians, Hannians (very similar to humans, by the way...).
