Notice that this contract has:
All under one contract address. How would one deploy all of these to one contract address?
Only one is actually deployed (EthermonData, in this case). It inherits from the other contracts.
EthermonDataBase inherits from some:
contract EtheremonDataBase is EtheremonEnum, BasicAccessControl, SafeMath
and then EthermonData inherits from that:
contract EtheremonData is EtheremonDataBase {
So the final contract that's deployed makes use of all of that code, but there's only one "contract" running.
See http://solidity.readthedocs.io/en/develop/contracts.html#inheritance in the Solidity documentation.
EthermonData.

EthermonData was deployed. Its code consists of code from a number of inherited contracts. (The source code could even include other contracts that it doesn't inherit from. The presence of those lines of code says nothing about what was deployed.)

EthermonData, it includes all the necessary code that was inherited. I don't know your programming background, but if you've used object-oriented programming languages before, it works just the same way.

The compiler generates EVM bytecode from the contracts. Contracts are just a higher-level concept just like classes in object oriented languages. EVM is not contract-aware.
Maybe you are confusing it with libraries, which are deployed and then called by relying contracts (using delegatecall) http://solidity.readthedocs.io/en/develop/contracts.html#libraries
