Answer 1

First register the device to GCM and get the gcm key. Send the notification to that device manually using the GCM key. Curl request to do so is

curl --header "Authorization: key=" --header Content-Type:"application/json" https://android.googleapis.com/gcm/send -XPOST -d '{"data":{"New message through curl"},"registration_ids":["<RegId1>"]}'

To send it using PHP go through following

GCM with PHP (Google Cloud Messaging)

I think you have to make a matching like user->reg id and store it in some storage on the third party server. After that you can pick a user and his reg id to send it to.
