But I want respsize of each categories in this result also it should be like:

                 {
                    "key": "50",
                    "doc_count": 87,

                 },
                 {
                    "key": "49",

Try this agg ;-)

"aggs": {
    "by_clients": {
      "terms": {
        "field": "clientname"
      },
      "aggs": {
        "by_categories": {
          "terms": {
            "field": "category"
          },
          "aggs": {
            "total_respsize": {
              "sum": {"field": "respsize"}
            }
          }
        }
      }
    }
  }
