A singer that can sing well but can't pitch high may only be able to sing in a lower range. This is common for many male singers, especially after they have hit puberty.

Sometimes but he is a singer what do you expect?
Anyone can be a singer, it just depends on which kind. Also, this depends on how good of a singer you are. If someone sings badly, they are less likely to be a singer. If someone sings well, then they are more likely to become a singer. Of course there are always, ways to digitalize someone's voice to improve the sound. However, this is not recommended.
The range between bass and alto is tenor
The friend is likely a musician if they like lyrics and sheet music. The friend is likely a singer if they need lyrics.

No, actually you can be a singer whenever you want. You just gotta start singing, being famous is a whole different, it involves the media and sometimes, whether you are good at singing or not.
