If I understand correctly you want to achieve a situation which when a new service request is created all 4 members of your Admin group will get the notifications regarding new service request.
In this case please go to Help Desk > Help Desk Settings and set a routing rule which assigns the Admin group (if you want all new service requests to be assign to the Admin group choose all categories).
Once you have set a routing rule make sure under Help Desk Settings General settings tab that the "Notify the Admin group assigned to the Service Request." field is checked.
I hope this information has been useful.
