Hi there - help please.
With regards multiple instances of the same 3d object.
Can each instance have a different model etc?

You can - see this dev post for some discussion on it:

In general, I don't really recommend it unless you have a good use case, since it can cause some confusion or extra memory usage if doing duplicated models (each instance will require storing all the model's textures.)
Can you say why you need to implement your game in this way?
