I cant tell you that I haven't created a google account in a number of years you might want to try theses could also be legacy accounts created before they started requiring first name and last name to create an account . It could also be an account merged from another email provider. you may want to try webmasters.stackexchange.com — Linda Lawton - DaImTo

Google only returns the data it has about a user so if the user hasnt filled the information out then the api isnt going to return it. Also some of this information can be set to private by the user namely birth date, in order for the api to return that data the user must have set their birth date to public in their profile.

The only advice i can give is to add fields=* to your request this should ensure that all of the data that google has is returned. Some of the Google APIs limit the response and require you to use the fields parameter on the call if you want additional data.
