I think the rulespretty fixed:
 * Alternate: every alternate, whether they are or not the same gender, have the same name, alias
 * Others: others characted wearing the same or close same name, even from other realities

Penelope and Peter Earth-4 are alternates of Spider-Man (Peter Parker, as he is the main character of the disambig), Ezekiel Man Spider is an other.

Even when the main character is a link to another disambiguation, the alternate fields are only for alternate of a character, not an identity, and are therefore unused.
