Basically you are creating panel with loop and assigning the same id to all the panel-group and that's what causing the problem here! So you can try working as below and please note ids should be unique in DOM

@{int i=0;}
foreach (var item in groupItem)
{
       <div class="panel-group" id="accordion_@i">
              <div class="panel panel-default" id="panel_@i">
                     <div class="panel-heading">
                           <h4 class="panel-title">
                                 <a data-toggle="collapse" data-target="#collapseOne_@i" href="#collapseOne_@i">
                                       @Html.DisplayFor(modelItem => item.Name)
                                  </a>
                            </h4>
                      </div>
                      <div id="collapseOne_@i" class="panel-collapse collapse in">
                            <div class="panel-body">
                                 @Html.DisplayFor(modelItem => item.IdNumber)
                            </div>
                      </div>
              </div>
        </div>
        i++;
}
