In this post you can see an approach for conditionally enabling/disabling a set of checkboxes. For this we can use the ng-disabled directive and some CSS clases of typeclassName-true and className-false:

<!DOCTYPE html>
<html>
<head lang="en">
    <meta charset="UTF-8">
    <title></title>
    <script src="../angular/angular.min.js"></script>
    <link href="../bootstrap/css/bootstrap.css" rel="stylesheet"/>
    <link href="../bootstrap/css/bootstrap-theme.css" rel="stylesheet"/>
    <style>
        .check-disabled-true {
            color: gray
        }

        .check-disabled-false {
            color: black
        }
    </style>
    <script>
        angular.module("atpModule", [])
                .controller("atpCtrl", function ($scope) {
                    $scope.selectedPrizemoney = 'Select one prize money';
                    $scope.isdisabled=true;
                    $scope.atp = [
                        { name: 'Nadal, Rafael (ESP)', rank: 1, age: '28', prizemoney: 66149345 },
                        { name: 'Djokovic, Novak (SRB)', rank: 2, age: '27', prizemoney: 70704129 },
                        { name: 'Federer, Roger (SUI)', rank: 3, age: '33', prizemoney: 84827704 },
                        { name: 'Wawrinka, Stan (SUI)', rank: 4, age: '29', prizemoney: 13155060 },
                        { name: 'Ferrer, David (ESP)', rank: 5, age: '32', prizemoney: 24034072 },
                        { name: 'Tsonga, Jo-Wilfried (FRA)', rank: 11, age: '29', prizemoney: 1708240 },
                        { name: 'Simon, Gilles (FRA)', rank: 26, age: '29', prizemoney: 760469 },
                        { name: 'Lopez, Feliciano (ESP)', rank: 20, age: '33', prizemoney: 1100579 },
                        { name: 'Benneteau, Julien (FRA)', rank: 28, age: '32', prizemoney: 617688 },
                        { name: 'Verdasco, Fernando (ESP)', rank: 33, age: '30', prizemoney: 689219 },
                        { name: 'Mayer, Leonardo (ARG)', rank: 25, age: '27', prizemoney: 946294 }
                    ];

                    $scope.shouldBeDisabled = function (item) {
                        if (item.prizemoney <= $scope.selectedPrizemoney) {                          
                            return true;
                        } else {                          
                            return false;
                        }
                    };
                });
    </script>
</head>
<body>
<div ng-app="atpModule" ng-controller="atpCtrl">

    <div id="atpPanel" class="panel">
        <h4 class="panel-header">ENABLE/DISABLE CHECKBOXES USING ANGULAR JS</h4>
        <hr/>
        <h5 class="panel-header">Select the maximum prize money:</h5>
        <select ng-model="selectedPrizemoney">
            <option>Select one prize money</option>
            <option ng-repeat="item in atp">{{item.prizemoney}}</option>
        </select>
        <hr/>
        <div ng-repeat="item in atp">
            <p class="check-disabled-{{shouldBeDisabled(item)}}">
                <input type="checkbox" name="{{item.name}}" 
                     value="{{item.name}}" ng-disabled="shouldBeDisabled(item)">{{item.name}}
            </p>
        </div>
    </div>
</div>
</body>
</html>
