Answer 1

Perspective . In a 3D engine this is typically achieved with something called a projection .

It looks like it's pretty easy to adapt AndEngine to do this: 3D Perspective Tutorial .

Answer 2

A simple approach is to scale the Sprite as it moves back in distance. Just treat the scale property as a Z depth. But beware of Z-sorting (when items in depth overlap). In a simple game like paper toss this will not be a problem. But for example, if your object passes through a hoop, you will find it gets hard to manage.

Answer 3

Look into the glTranslatef(), glScalef() and glRotatef() functions in OpenGL ES as you'll be using all of these to get the effect you're looking for.
