To validate name array dynamic input text boxes , You need to mention array input field's index like following.

<input type="text" name="qty[0]" class="input-text" />
<input type="text" name="qty[1]" class="input-text" />
<input type="text" name="qty[2]" class="input-text" />

Suggestion by @BornCoder is to create new validation for that.

Good solution is to check if one validation method can handle that situation: http://inchoo.net/magento-2/validate-custom-form-in-magento-2/ I prefer to start by use: validate-grouped-qty (because of name of input provided in example but this is only to start search)

Full solution: There is only some location, where validation rules exist out of box: SHOP/vendor/magento/magento2-base/lib/web/mage/validation.js SHOP/vendor/magento/magento2-base/lib/web/mage/validation/validation.js And of course , provided by jQuery. Check it or write custom. No more ways to accomplish task in frontend by using native solution.
