RAML to send multiple files to Mule api/endpoint could be defined as mentioned in answer to the post below-

Send multiple Files in HTTP request using RAML

To read these files in Mule api,you can use a for-each construct,something like below could be useful:

<foreach doc:name="For Each" collection="#[message.inboundAttachments]">
       <set-payload value="#[payload.dataSource.content]" doc:name="Set Payload"/>
       <byte-array-to-string-transformer doc:name="Byte Array to String"/>
       <logger message="Content :- #[payload]" level="INFO" doc:name="Logger"/>

</foreach>

Once read you can edit or transform the file as required and add it as attachment using set-attachment

<set-attachment attachmentName="requiredFile.xml" value="#[payload]" contentType="text/xml" doc:name="Attachment"/>

And then you can send it to required FTP connector.
