Is my first passagio the point where I have to go louder with my chest voice? If so, I have to get louder at G4! I can sing quietly at E-F-F#4, but from there on I have to get louder! Im I a tenor voice?

I can't give you an estimate on your vocal fach until your voice has completely broken and has time to settle. Let puberty do its work first.
