Yes, if you mean a red dwarf, not a red giant, and if the planet is
situated so it gets about as much heat as Earth does. However, such a
planet would almost certainly become tidally locked before life could
evolve on it. Then its atmosphere would freeze on its night side,
leaving the day side in vacuum.

I'm at work^W^Wtoo lazy to do the physics and math now, but what kind
of year length? If the planet were in a 3:2 resonance lock, like
Mercury, would the days and nights be too extremely long?

(And would an orbit around a close gas giant be stable?)
