Some background information, such as, geographically where these pieces were found would be helpful.
Were they found at the same sites, what is the background history of each site.

As Silver Searcher has already mentioned, these buckles are likely post-1900 in date.
Most of these are ladies sash buckles, the last one pictured with the rust on it is a horse harness buckle.
