If its not a problem can you share your workbook on tableau public.
As you've found this kind of small multiple is not a built-in feature of Tableau. To get individual labels you have to add a dual axis and write some more calculations, see the workbook by Andy Kriebel for an example: Tableau Tip Tuesday: How to Create Small Multiple Line Charts.
If you have a dashboard that won't change / be affected by user filters, a cheesy way to do this would be to create a bunch of floating text objects with titles and position them above your graphs. Have your rows as individual sheets, place them all on one dashboard with a blank object in between each and drop the floating text objects with titles in the space created by blank objects.
