Clare looked to be about 8-10 when she met Teresa. Teresa was already an adult. She didn't appear to be still be still maturing physically, the way we see Priscilla and Clare throughout the series.

Let's assume Clare is 15 at the beginning of the series. By the end, she’s 22.

Let's assume each generation is 10 years, for easier math:

Teresa would've been in her 20s, let's extrapolate from that that Ilena was in her 30s by the end of the series.

Rafaela was an adult when Teresa was still a trainee. Between Luciela and Teresa as number 1s, there were at least two other number 1s: Hysteria and Rosemary. Rosemary was rising in rank at the same time as Teresa. Rafaela then wouldve been in her 30s when she met Teresa as a trainee.

Riful is much older. There have been many number 1s that we never learned about besides names and perhaps more who simply disappeared in history. Number 1s awakening is rare, given that by the start of the series, there are three on the continent and Priscilla who is beyond the ability of an abyssal one.
