                jsonBody.put("name", name); 
                jsonBody.put("family", family); 
                //request a json object response
                JsonObjectRequest jsonRequest = new JsonObjectRequest( Request.Method.POST, url, jsonBody, new Response.Listener<JSONObject>() {
                    @Override
                    public void onResponse(JSONObject response) {


                    }
                }, new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                    error.printStackTrace();
                    }
                }) {    //this is the part, that adds the header to the request
                    @Override
                    public Map<String, String> getHeaders() {
                        Map<String, String> params = new HashMap<String, String>();
                        params.put("Content-Type", "application/json; charset=utf-8");
                        return params;
                    }
                };
                // Add the request to the queue
                Volley.newRequestQueue(Activity_Goods_List.this).add(jsonRequest);
            } catch (Exception e) {
                Toast.makeText(getApplicationContext(), e.getMessage().toString(), Toast.LENGTH_LONG).show();
            }

Answer 1

Add your objects to array-like this

Let us assume you have a list of names and family

    JSONArray request=new JSONArray();
    for(int i=0; i<names.size; i++){
        JSONObject jsonBody = new JSONObject();
        jsonBody.put("name", names.get(i));
        jsonBody.put("family", family.get(i));
        request.put(jsonBody);
    }
    // You'll have array ready here for your request

You can send as a json array. Encode the Array into JSON and sent to your backed. From your backend, you can parse JSON and retrieve back the array. You can't directly send the array, You have to follow data transfer formats like json or xml
