We are very small business firm like less than 10 people. I planning to setup new server. Initially I thought install AD, DNS, DHCP, DC and Exchange on same server. Microsoft not recommending all in my server Installing Exchange on a domain controller is not recommended.

So give me suggestion, Is it OK install everything on server for small company like us? or 

create 1 virtual and install Exchange on that server and rest will be on base?. 

Go virtual.

I've installed many Exchange servers for my customers. Since Exchange 2010 I've installed only virtual and never a single physical Exchange server.

As far as Exchange on DC is concerned, like it says in the recommendation, definitely not recommended.

And while you are at virtual, create separate volumes for mailbox database and mailbox log. That's the best practice.

Hi,

It is not recommended to install Exchange server on a domain controller. You can create a virtual Exchange server, there is a lot of planning that goes into constructing a virtualized Exchange infrastructure, with the primary consideration being hardware allocation and fault tolerance. Concerning these factors will guide you to a solid and reliable infrastructure.

For more information, here is a blog for your reference.
