Your backend knows:
- the age
- the username

Now, when a device registers use the username as the alias value. Using an
alias on _device registration_ (E.g. username or an email address) is
already part of the Cordova example:
https://github.com/aerogear/aerogear-pushplugin-cordova#sample-example


Now the sending part:
Your sever can do the query "select all usernames under 40 years", where
you get a list of usernames. Use these queried usernames as part of the
SEND, like shown here:
https://github.com/aerogear/aerogear-unifiedpush-server#sender

Or a bit more detailed our message spec:
http://aerogear.org/docs/specs/aerogear-push-messages/

No for apple. if 'alert' is included, the OS displays the message. However,
you should be able to send messages without an alert. Parse the details of
the message and if you like (e.g. some rules are true), notify the user.
