Answer 1

There are many ways you can Achieve it

You should take a look at Firebase Cloud Messaging (FCM)
It would help you create a Real time Chat Feature between a Single User and Multiple User

Also with Firebase Storage Capability you can also provide feature like Uploading Pictures and Videos
