It's a tenet that life is an exception to that law and this is accepted because the global entropy doesn't stop increasing because of the creation of law.
2) About the second question, the photosynthesis reaction can be seen as the bridge from inorganic to organic world. It absorbs energy from sunlight, so it is endothermic. If the entropy of the reaction products (C6H12O6 + 6O2) were lower than that of the input molecules (6CO2 + 6H2O) the process would not be spontaneous as it is. So, while the living cell seems more organized than its inorganic origin, its entropy is really bigger.
Entropy of a system can be reduced by adding energy from outside of the system. Hence life is not an exception to the law.
according to the big bang model, the entire universe was at first a dense and hot spot. And now we have hot parts (the stars) and cold parts (the planets and other non radiant bodies). It seems against the second law, because for an uniform temperature universe to become what it is now, heat was transferred from colder to hotter parts.
Unless that hot and dense spot was not homogeneous.

If you consider the universe to be an inert gas, as it expanded, it should cool down.The temperature of the whole universe should now be about 2.7K.
