Statement (1) is right.
When the charged sphere in put inside the container, its +ve charges raise the potential of the container and the electroscope. Hence, the gold-leaf diverges. When the sphere touches the botom of the container,all its +ve charges is conducted to the outside of the container. After the sphere is left, the +ve charges on the container provides a potential for the gold leaf to remain divergent.
Statement (2) is right.
As said in above, when the sphere touches the bottom of the container, all its +ve charges are conducted to the outside of the container. Thus the sphere becomes neutral.
Statement (3) is wrong.
Since the container is a conductor, all charges are residing on its outside. There is no charge on the inside of the container.
