meaning of 'Nummer' and 'jeweils' in a sentence?

Question

What's the meaning of Nummer and jeweils beneath?
I know what Todesrad is, but not what the Nummer means here. And does mit jeweils 4 Personen mean with 4 persons each time?

Der Mitarbeiter wird mit Wirkung ab 04. März 2011 die Aufgaben von Artisten mit folgenden Tätigkeiten übernehmen: Hochseil- und Todesradnummer mit jeweils 4 Personen (gesehen wie auf dem Video bei Youtube vom 20.02.2010)

This is the deepl translation ==>

Effective March 4, 2011, the employee will take over the tasks of artists with the following activities: High wire and death wheel number with 4 persons each (seen as on the video on Youtube from 20.02.2010)

Answer 1

The "-nummer" is a suffix to describe a circus act. The correct translation of

Hochseil- und Todesradnummer

would be

tightrope act and wheel of death act

For "jeweils", your translation already contains the right meaning.

Jeweils 4 Personen

is translated as

4 persons each

This shows that both acts (the tightrope act and the wheel of death act) are performed by a group of 4 artists.
