Yes you can as long as your iphone is connected to the same iTunes account you bought the apps on.
If its an iPhone then download iTunes (if you haven't already) and plug both of them in using a USB charger. Then sync the apps off you iPod on to the computer, then simply click and drag them into where it says iPhone.
Although iPads can download apps made only for iPhone/iPod Touch, the iPhone can only download iPhone or iPhone/iPad apps. Apps made only for the iPad do not appear on the App Store. Luckily most of these apps have an iPhone counterpart such as Angry Birds (iPhone) and Angry Birds HD (iPad only).
