Can i select multiple object with apple pencil?

If by multiple objects you mean two individual drawings or similar then you select one, hold a finger on the selection and tap to select the next object. Works with a standard stylus on a non-pro iPad so I'm only guessing it might work with the Apple pencil on the iPad pro.

I don't think so, but then I'm not really sure that Pages has a way to select multiple objects other than to include all those inside a selected region.
