Foam is typically lighter than plastic due to its low density and air-filled structure. This makes foam a popular choice for packaging materials and insulation where weight is a concern.
Polyurethane (PUR and PU) is a polymer composed of a chain of organic units joined by carbamate (urethane) links. While most polyurethanes are thermosetting polymers that do not melt when heated, thermoplastic polyurethanes are also available. Polyurethanes plastic commonly used in the manufacture of flexible, high-resilience foam seating; rigid foam insulation panels; microcellular foam seals and gasket - in.kompass.com/a/bottles-plastic-for-the-pharmaceutical-and-cosmetic-industry/2071009/

Lead is a heavy metal that is dense and has toxic properties, while plastic foam is a lightweight material made from expanded polymers. Lead is harmful to health and the environment, while plastic foam is commonly used in packaging and insulation due to its lightweight and insulating properties.
Assuming the foam is from furniture stuffing, then the answer is no. Such foam is plastic and is definitely not edible.

Unable to say, as this will depend on the plastic resin, the filler material, if a blowing agent was used to foam the plastic, and the size/shape of the object.
Originally a brand name for polystyrene foam, "styrofoam" is used as a generic term for beaded or extruded plastic foam material.
