I am getting one value by JSON array, but how can I store multiple values in JSON array and how can I retrieve it by JavaScript?

I think you are getting only 5 in your second combo because you are making an error in your loop. You could do

//in combo1.jsp

String selectedValue = request.getParameter("count");

Map options = new Map();
 //get your data from db
while(rs.next()){
    String t1=(String)(rs.getString(1));
    options.add(t1, t1);
}
String json = new Gson().toJson(options);
response.setContentType("application/json");
response.setCharacterEncoding("UTF-8");
response.getWriter().write(json);


    //to get data
    $.getJSON('combo1.jsp', {
        count: this.value
    }, function(options) {
        var dropdown2 = $('#combo1');
        $('>option', dropdown2).remove(); // Clean old options first.
        if (options) {
            $.each(opts, function(key, value) {
                dropdown2.append($('').val(key).text(value));
            });
        } else {
            dropdown2.append($('').text("Please select dropdown1"));
        }
    });
