Has a very light (less than 1eV) Higgs mass been excluded by theory and/or experiment?
Could the Higgs mass be very light (< 1ev)?

Yes. Masses up to at least some 90 GeV have been excluded by existing experiments, see for example HIGGS BOSONS: THEORY AND SEARCHES; Bernardi, Carena, Junk.

An extremely light Higgs (less than < 1ev) would be a catastrophe in astrophysics. Top amongst many other problems, it would destabilize stars like our own Sun.
