I started a little bit of Googling around the topic, and found very few information. There are mainly upper limits. I found lower limits only to the rest mass differences of the different neutrino flavors.

Thus, what are the actually current known lower mass limits to the neutrino flavors?

The lower mass limits of neutrinos is not 0eV. They have to have a mass, since we can observe neutrino oscillations. This is something the standard model did not get right. Looking at PDG (2014) the boundaries seem to be 0 < m < 2ev.

The three masses of the neutrinos are: .04ev/cc, .08 and .12. These are not limits, up or down, these are the masses. It should be noted that the differences are the mass states.
