How do I Create Object - Families

I am trying to Spawn / Create randomly a Family with 3 Objects inside.

Here is the screen shot. If I create a single object like this lets say a apple.png it works fine but if I use Families its not. Is it even possible to create Spawn Families?

If you put the three objects into a container they will all spawn when one is spawned.
