Does Meissan Porcelain Factory manufacture miniature porcelain dolls?

if you break it and the store owner bangs you up and down! LOL just kidding...

Porcelain

wrap them carefully with newspaper and see if you can get some foam penuts and store them in boxes

It could be stored in the attic but put it in a box or a container so the dust won't cover the doll

No-- avoid places that the temperature is not regulated.
