Yes, an object can cause multiple shadows if there are multiple light sources casting light from different angles. Each light source can create its own shadow of the object.

If there happens to be a bright light shining on an object, that object's 'shadow' will cast itself on whatever is around it. +++ More simply, the "something" is the object blocking the direct light from the source. The air scatters the light so the shadow is not very dark - on the air-less Moon a shadow is fully dark.
