Will an exemption also protect the exempted user from being detected with any of the other users from the same multiple account group?

If I have a multiple account group with 4 accounts using the same computer and I add an exemption for 2 of those users, will this exemption protect the exempted user from being detected with any of the other users from the multiple account group also?

No, an exemption is valid for both exempted users together only. If you want to exempt additional members of the same multiple account group you have to also add additional exemptions for them.
