A few old figures I need assistance with..

Hello. I recently acquired a very large collection of old figures and statues and have been wanting to catalog them. I have gone through a majority of them and there are a few that I have not been able to identify at all. The two Hummel figures I have looked through a few catalogs and had no luck finding. The black boy playing the flute to the horn feels like it's made out of ivory, and the geisha as well. The bird on the nest is detachable and both parts are quite heavy so I'm assuming they are bronze. The poodle is just heavy, so might be pewter? I am not sure. Finally, the dog  If anyone has any idea about any of these it'd be greatly appreciated.
