1) to put every site on same ip with name servers (for example site1 and ns1.site1 and ns2.site1 on ip1, site2 and ns1.site2 and ns2.site2 on ip2, etc...).
2) to use 3 ip's to spread sites on them and 2 ip's for name servers (in this case every site would be on ns1.site1 and ns2.site1).
3)to use all 5 ip's for sites and name servers but name servers on different ip's and domains (on first ip: site1, ns1.site2, ns1.site3 second ip: site2, ns1.site1, ns2.site3, third ip: site3, ns2.site1, ns2.site2, etc.)
4)some other variation you think it's better...
Directly linked sites would be on different ip's of course.
