Then, do smells rise or sink?

This is because the compounds you are smelling are entering the air, making their way up your nose, to your olfactory system. So, from this perspective it rises.

How far do smells travel?

If we assume that the average mass of air (since it is a mixture of different gases) is 28.9 g/mol (or each gas particle is around 4.799*10-26), and room- temperature is 27C or 300K, we find that the average velocity of a single air particle is around 500 meter/sec or 1800 km per hour.
