I don't see my contact names on my ipad, just their phone numbers

Go into Settings > Contacts and there select an account that you want to use to manage your contacts. Make sure that when you select that account, you see that “Contacts” is turned on to sync those. If there are other things you want to sync as well, make sure they are turned on too. Make sure that you have all the accounts on your iPad that you also have on your MacBook and your iPhone as a different account other than your AppleID could be what has all your contacts. For instance, my contacts all sync from Google, I don’t see the contacts on a new device until I sign that device into my Google account and make sure that the Google account is set to sync all that information.
