I have created chat system in firebase and now i want report on daily,weekly,monthly that how many users are exchaging how many words and how much time they are engaged with app,
There is some reporting of message delivery in the Firebase Cloud Messaging console.
If that isn't enough for your needs, you may want to connect Firebase Cloud Messaging to BigQuery. After you do this, Firebase will write delivery data into BigQuery, where you can query it. The documentation includes some example queries to get you started.

I am developing a quiz app for Android, I use Google Firebase for my database, the purpose of the game is to ask a question from the players and the person who answers the question first wins the game. At a certain time of the day, the database automatically generates a question and sends it to the participants.
The quiz must be sent at the same time to all connected users, how can I synchronize the submission of the question to all users ?
You can subscribe all the users to a specific topic when they sign up and you can use Cloud Functions to send the notification to the topic.
All users subscribed to the topic should receive the notification.

I want to show in my app, how many users are online. I tried to find solutions but the solutions that i found is generally in web, i have mobile app and i want to show how many users are online. Can someone please help?
From the firebase documentation. Firebase has the functionality to monitor presence in the application. RTDB supports it natively, but Firestore leverages other services to implement it.

I want to make a chat app in which all features of chat like messaging, sharing video, image, and emoji, etc. I found a lot of tutorials for that but no one says how to chat with only those you know or have in contacts to prevent unwanted disturbance to the users from others. How to make such an app with flutter?
One way is by reading all the contacts number form the phone and then check if that phone number is registered
One feature/method I can think of is using referral/invite. The person can only join the app only if he is invited and the invitation is approved by the admin. This way you can have control over who accesses your app.

I've migrated an Android app from Google Analytics to Firebase Analytics. The Firebase Analytics console shows data from the time I migrated. But it does not show any of the historical data which is still in Google Analytics.
How can I import this historical Google Analytics data, so everything shows up in Firebase Analytics?
There is currently no API to import historical data into Firebase Analytics.
If you think this is a feature that many developers might need, you can request it here.
The best way to get data from Google Analytics to Firebase is by importing data to Big Query and then merging the data. Big Query lets you perform in depth queries on your data too.

I am going to develop Chat applications for android. There are two methods FCM(Firebase Cloud Messaging) and WebSockets. Which one is easy to develop and which will be higher in performance in realtime?. I want to implement images, Videos, Audios sharing features too. So Please suggest me good method to develop.
Here is a complete chat project
You should fill it with your firebase credentials to get it working, the source code is simple to understand and you can easily update the features. This project already has some features built with it.
Firebase provided you to realtime database and simple data in real time database. I think you should be better using FCM.
