Your need to use ng-style. Here is your example in JSFiddle http://jsfiddle.net/2raw9xhq/2/

<div ng-app="" ng-init="names = [{width:'78%', 'background-color': 'green'},{width:'60%', 'background-color': 'red'},{width:'50%','background-color': 'blue'}]">
<div class="statarea" ng-repeat="x in names">
     <div class="ratingarea">
        <div class="your-rating">
            <span ng-style="x" class="outer">{{x.width}}</span>
        </div>
    </div>
    <div class="clear"></div>
</div>

You can use ngStyle as other Angular built-in directives, for instance

ng-style="{color: myColor}"

ngStyle needs an Expression which evals to an object whose keys are CSS style names and values are corresponding values for those CSS keys. So in your case, you can set the width like

<div class="statarea" ng-repeat="x in names">
  <span ng-style="x" />
</div>

Or use scope variables like

<div class="statarea" ng-repeat="x in names">
  <span ng-style="{'width': x.width}" />
</div>
