How old are the BTR characters? (Corrected)

[They deleted a recent post lol]

It may seem silly, and it is. But it's just something that crossed my mind because of the indicated image. And it is based on the manga, which is from 2017, that is, canonically, the characters would be very old today. While the anime happens in 2022, which is 5 years apart. I don't know, I just want to see your answers.
