1. How to draw a polygon

To display a polygon use a shape directive with name attribute set to polygon:

<shape path="{{vm.paths}}"  name="polygon" ></shape>

2. How to get a marker position via Google Maps Drawing Manager

vm.onMapOverlayCompleted = function (e) {
    if (e.type == google.maps.drawing.OverlayType.MARKER) {
        var pos = e.overlay.getPosition();  //get marker position
        alert(pos.toString());
    }
};  

Modified example

var app = angular.module('myapp', ['ngMap']);
app.controller('DrawingManagerCtrl', function () {
    var vm = this;
    vm.paths = "[[28.646359, 77.259623],[28.645153, 77.207438],[28.680098, 77.120921],[28.680098, 77.259623]]";


    vm.onMapOverlayCompleted = function (e) {
        if (e.type == google.maps.drawing.OverlayType.MARKER) {
            var pos = e.overlay.getPosition();
            alert(pos.toString());
        }
    };
});
