You can check out the angularjs documentation here: https://docs.angularjs.org/api/ng/directive/input

For example, if you want to validate text boxes, you can have something like

<form name="validationform" ng-submit="submit()">
    <input type="text" name="value1" ng-model="textinputvalue" ng-required>
    <input type="submit" id="submit" value="Submit" />
</form>

(and similarly for the other input boxes)

If you are looking to set a custom validation, there is a really good answer here that you can look at: How to add custom validation to an AngularJS form?
