I had a look at some other Thom's directories between the late 1840s and early 1900s for details of the Glass bottle connections, and the only mentions of John that I see are in 1904 and 1894. Note - only shop/business owners and prominent residents are listed in these directories. :
1914 - 83 Thorncastle Street, Ringsend
Hibernian Glass Bottle Works
E. & J. Burke & Co. Ltd, Wm. Hixon manager
1904 - 83 Thorncastle Street, Ringsend
Hibernian Glass Bottle Works
E. & J. Burke & Co. Ltd, Mr. Anthony Cassidy manager
John Little is listed in the index as Glass bottle manufacturer, Ringsend (not specifically mentioned at the address)
1894 - 83 Thorncastle Street, Ringsend
John Little, bottle manufacturer
Hibernian Glass Bottle Works
1884 - no 83 does not exist, and no mention of either the Hibernian Glass Bottle Works or John Little as a bottle maker.
Found a possibility for the Stanley photographer in the street listing in one edition of Thom's (1904) at the same address later listed as Stanley & Lauder :
E.J. Stanley photographer, 22 Westmoreland St
He may not have been in business under his his own name very long as an earlier directory (1894) shows the address as E. & J. Lauder (Lauder Bros) and the later listing in 1914 shown is as E.J. Stanley & Lauder Bros - it's not clear if they operated as partners or as separate businesses in the same address.
