Jupiter's Europa, Saturn's Enceladus and Titan have the strongest evidence.

The Asteroid Ceres has joined Mars and several satellites of the giant planets in the list of locations in the solar system that may harbor life. The dwarf planet has water. Now, infrared spectra taken from the orbiting Dawn spacecraft reveal organic-rich regions in and around its ~50-kilometer Ernutet crater. Ceres definitely has about 25% water ice, but there is a reasonable likelihood that there is liquid water as well.

Mars also has a lot of water ice for sure but some of it could be liquid.

Recent spacecraft studies of Comet 67P/Churyumov-Gerasimenko with Rosetta and of Ceres with the Dawn space probe provide evidence that complex organic molecules and even amino acids are ubiquitous on small bodies in the solar system and that water ice is abundant in the asteroid belt.
