Hi dear, it is enough to draw incident rays parallel to principal axis. That ensures that the object is at infinity and no need to draw an object at all.
No the weight of an object has nothing to do with friction. Weight is the gravitational attraction of the object and the planet.
then it will make an image of that object between C & infinity, which is magnified then the object.
The image produced is a real image if the object is located at infinity and the lens is a convex lens. The produced image can actually be placed on a screen and photographed.
The weight of an object is the force of gravity.

An object in space having a volume that is approaching zero and density approaching infinity?
No the weight of an object has nothing to do with friction. Weight is the gravitational attraction of the object and the planet.
you take the weight of a house and multiply it by infinity then multiply by infinity again
then it will make an image of that object between C & infinity, which is magnified then the object.
A ray.
A ray.

Zero.
The mass of an object does not change , but its weight can vary.
If the object is floating, then the buoyant force is equal to the object's weight.
