There is an issue with your Json. it is not in proper format.
Your json is throwing error at
"profileimageurl": "http:\/\ddd\/lms\/pluginddddfile.php\/5\/user\/icon\/f1"
you have to fix your json first then search in your json for full name. You can fix your json like "profileimageurl": "http:\/ddd\/lms\/pluginddddfile.php\/5\/user\/icon\/f1" i-e removing \ from http:\/\
or by adding / this to your url http:\/\/.
Further for next time if you test json first check is your json correct or not ? there are many tools available online to test your json such as this tool after fixing the issues in json you can access it as said by Konstanin D

First issue try to correct 

"profileimageurlsmall": "http:\/\/ddd\/lms\/dd.php\/5\/user\/icon\/f2",
"profileimageurl": "http:\/\ddd\/lms\/pluginddddfile.php\/5\/user\/icon\/f1",

Then your json object has no key fullname You need to use json[0].fullname

       $.ajax({
                 url: "url",
                 dataType: "json",
                 type: "POST",
                 success: function(data) {
                 var json = $.parseJSON(data);
                 console.log(json[0].fullname);
                 }
        });

This is an array so to get the fullname of the first array member you have to do:

json[0].fullname
