Yes there are. 5 if five to everybody and seven to nobody.
15 m is 15 m to everybody and 12 to nobody. Perhaps some number
is not known to everybody but that does not affect the number itself.

Note that you didn't specify for whom. They are the same for everybody.

That number is the same for everyone. Pernhaps the duration in Earth frame
is uniteresting or unknown to someone but that does not affect the number.
