Answer 1

First get uid of the current user that is logged in:

FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
String userid = user.getUid();

then retrieve the data of the current user:

DatabaseReference ref = FirebaseDatabase.getInstance().getReference("Users");
ref.child(userid).addListenerForSingleValueEvent(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) { 
String name = dataSnapshot.child("name").getValue().toString(); 
name1.setText(name);
}

Assuming you have this:

Users
  userid
     name: peter
     //etc
