I'm fairly sure the numbers are as follows, and all in KB:
documentSize: Size of the document
documentsSize: Combined size of all documents in collection
collectionSize: Combined size of all documents in collection, along with overhead such as indexes
x-ms-resource-usage is about consumed resources within the collection, while x-ms-resource-quota is going to give you your limits. So with quota, you'll see documentsSize and collectionSize both set to something like 10485760, which is 10GB (10,485,760 MB).
