The closer the light source is to the friend, the bigger the shadow will be. The further the projector is from the wall where you are projecting, the bigger the shadow will be.
No change will occur because shadow is a dark outline of an object, irrespective of the colour of the object or the colour of the light.
The shape does not change, only the length, depending on where the light comes from. Such as on a sundial, and the shadow gets longer or shorter over hours.
The lower the sun in the sky, the longer the shadow. A shadow is always cast in the opposite direction of incident sunlight. When the sun is directly overhead (at noon) the shadow is shortest.
I'm pretty sure that... Shadows change when the angle of light shining on the object changes. Eg. A person standing in the sun just as it rises will have a longer shadow facing west because of the angle that the sun is at. Whereas the same person standing in the same spot at midday will have a shorter Shadow so the shadow will make the person look shorter. If the light (sun) is directly on top of the person, they mah have no shaddow.
There are many things that could happen when an object is moved nearer to a light or further away. It could change temperatures.

a silhouette is a shadow or a void of an object or something. At the best it is more than a shadow, it is mastered by an artist skilled in hand-cutting portraits from viewing. At the worst, it is a tracing of a shadow, or a photo-shop. The word silhouette came from Augustin Edourt who changed the term "shades" which were often wall tracings, to silhouette after the authentic hand-cut profiles Etienne de Silhouette admired. silhouettesbycindi.com
