Answer 1

You can user scripted update(documentation link) for your requirement.

1. Query to add value in hobbiles

   {
       "script" : {
           "source": "ctx._source.others.hobbies.add(params.hobby)",
           "lang": "painless",
           "params" : {
           "hobby": "reading books"
        }
      }
   }
   

   
   

2. Adding a new field in others

   {
       "script": {
           "source": "ctx._source.others.location = 'value_of_new_field'",
           "lang": "painless"
       }
   }
   

   
   

3. Remove cricket from hobbies

   {
       "script" : {
           "source": "int index = ctx._source.others.hobbies.indexOf(params.remove_string); if(index != -1){ctx._source.others.hobbies.remove(index);}",
           "lang": "painless",
           "params" : {
               "remove_string" : "cricket"
           }
       }
   }
