You have an old iPad that uses a very old version of iPad OS. It may be too old to download any of the apps, even if you could open the store. What happens when you try to open the App Store? The link below offers suggestions of what to do.
If you can't connect to the App Store, iTunes Store, or other Apple services - Apple Support
