Is it possible for two or more apps under the same project to receive push notifications with the same server key? If so, how can this be done?

I'm about to develop an app similar to a birthday reminder and I plan to use firebase for push notifications but what makes me second question my choice is whether users will be able to receive a birthday notification if they are offline(not connected to internet for the whole birthday day). I know firebase has some offline persistence support but I'm not sure if this includes push notifications support. Are there any options to achieve that with firebase or with any other tool compatible with react native?
If the device is not connected to the internet, it is going to be impossible to deliver messages to it through Firebase Cloud Messaging or other internet protocols.
The common way to deal with such a scenario is to deliver the message to the device when the user does have an internet connection, and then only display it once it's the right time. By sending a data-only message through FCM, your application code controls exactly what happens with the message data.
There are essentially two types of notifications: in app messaging and cloud messaging. Both are offered by Firebase: In App Messaging and FCM (Firebase Cloud Messaging).
The details you've given about your app is a little bit vague but if you're asking for push notifications, then FCM does the job. FCM will send notification when the app is on background or killed (exited out). When you say device is offline I'm assuming you mean when the user isn't using the phone. Yes, the notification will still come.

I am coding a React Native app and I using Firebase push notification service.
In my app, users can send message for each other and I want to notify them when they get message.
I found one way for native android I can code for react native it is not problem just I want to know if there is better way. I can make post to directly to Firebase service with using Http post.
This is the link which way I found: https://blog.usejournal.com/send-device-to-device-push-notifications-without-server-side-code-238611c143
I want to push notification to specific device without server, is there another way to do this?
Sending a message to a device with Firebase Cloud Messaging requires that you specify the FCM server key. As its name implies, this key is supposed to only be used in trusted environments, as knowing it allows one to send any message they want to all users of the app. For this reason it is not possible to secure send messages directly from one device to another device with FCM.
Instead you will have to run code in a trusted environment, such as your development machine, a server you control, or Cloud Functions. Your client-side application code invokes the server-side code, that ensures the call is authorized, and then calls the FCM API.

I want to show notification in my app even if the app is closed.. I don't need Firebase's Push Notification Service. The idea is similar to WhatsApp's message notification service.
When a value is added to firebase by a user another user should receive notification that there is a value change
Can someone tell me how this is done and What should I use to achieve this?
Push notifications for all major apps run through APNS for iOS, and Firebase Cloud Messaging for Android. While the apps may use a higher-level service from their application code, those services depend on APNS and FCM for the actual message delivery.
To see an example of how to build a notification system on top of this, based on values being written to a database, see Send Firebase Cloud Messaging notifications for new followers.
I need to configure push notifications for an Ionic 2 application for android devices.
I read here that in order to do that you need to login to Firebase console, create a project and so on...
So my question is, do I really need to log into Firebase to do this? I'm not using firebase in my app, so I don´t get why I need to create a project to get a SERVER_ID and SERVER_KEY. What if I delete that project in Firebase afterwards, then my push notifications will stop working?
Thanks
Yes, you do need an account to use Firebase Cloud Messaging because you'll need a key to send pushs.
You need the key to use device-to-device push via HTTP and you need a project to send notifications to a group or topics.
I don't think that there's a way to use push without creating an account in any service.
You don't need a Firebase account.
You can use azure notifications hub or amazon aws or google cloud service, ionic cloud, etc.
Any cloud services that provides a notification hub which is basically a server for receiving and redistributing to the registered parties to the specific platforms.
Please note that some of these are specifically mobile oriented meaning you wont have to write any server side code and others aren't.
Is there any way for a LoB UWP app to receive push notifications without using WNS or being registered to the Store, e.g., from a local server?
You can setup socket connection between your application and server side and handle any information in foreground or background task
