separate class for getting IEnumerator or implementation IEnumerator inside are not needed

[seniorwebdeveloper2]

Making PeopleEnum class is not needed, when you use foreach without custom sort of output. Instead of it just call GetEnumerator() from _people. _people - is array of Person objects. And arrays of any kind of object have GetEnumerator method.
Write public IEnumerator GetEnumerator() in next way:
{
return _people.GetEnumerator();
}
Class PeopleEnumClass is not needed and may be deleted.
