I just want to sync music from iTunes in my PC to iPhone

Yes.

Instructions here => Use iTunes to sync your iPhone, iPad, or iPod with your computer - Apple Support

Did you read the link (in blue) in my previous post? What you can sync with iTunes

• Albums, songs, playlists, movies, TV shows, podcasts, and audiobooks.
• Photos and videos.
• Contacts and calendars.

iTunes features might vary by country or region.

You can sync onto your iPhone but not to someone iPhone.

Thank you, yes I did but I am trying to sync my music to another person’s iPhone but do not want to sync others things like app, photo, messages, movies, tv shows…etc.

You can't do that.

You can lend the CDs to them and let them sync themselves on their computer.

You're welcome.
