Need help restoring metal cistern cups from 1800's

I have some metal containers (cistern cups) that are the water carrying cups from an old cistern that was at my grandmothers house. This was a series of cups that were lowered into the well of collected rain water by a gear and handle mechanism whereby the water was then emptied into a spouted container for collection in a bucket. I am uncertain as to the content used in such metal. It appears to be galvanized metal, has a few rust spots since it has been stored outside, and holds a magnet with firmness. I would like to use these cup/containers for other uses, such as pierced votive candle holders, small outdoor electrical lights, or other decorative uses. Since I am not certain as to the expected content of the metal which probably dates to the late 1800's, I am concerned if sanding, piercing, or general use may present any health problems. Also what is the best paint or finishing coat to use. I would appreciate any information from experienced metallists....Thanks

Since these are an antique (over 100 years old), I would not harm them by altering them- instead I would polish them or restore them to near original state or use as is- sometimes restoring ruins value.

Usually, I am all for re-purposing but not by altering antique treasures. You could use them as a rain chain or find other uses without drilling or harming them.

I would encourage you to follow the old rule of first do no harm- works for antiques as well as in the medical profession.
