I have to run differents services in a lab enviroment where I'll have 6 computers working as servers, what services can I put together, and what cannot be, in order to prevent security risks, and considering that if one service goes down, affects less possible the function of the server farm, the services are:
- MySql
- Http for intranet
- Https
- DHCP
- IPP
- SMTP
- LDAP
- VPN
- SSH
- NTP
- DNS
- NFS
I'll use linux
How long is a piece of string?

. At the very least you're conflating security and redundancy (which is Bad). All we can really offer you is the general rule: Separate your services logically, and have two of everything for redundancy...
