GroupDocs.Metadata API provides the feature of adding custom properties to the PDF documents (requirement #3). For details, please visit this documentation article.

For the rest of your requirements, I would suggest you to use Aspose.PDF which is offered by our sister company Aspose. This API allows adding/retrieving attachments to/from PDF documents. Fortunately, Aspose.PDF also allows working with the custom properties in PDF documents (see this), so this can be an all-in-one solution for your requirements.
