Put the required stuff in
truffle-config.jssuch as Infura key -
npx truffle migrate network --rinkeby
Result
Some data is stored in .openzeppelin/rinkeby.json
Some data is stored in build/contracts/AppleCoin.json and OrangeCoin.json
Does it mean I need to keep build folder in the repo to keep track of deployments?
(currently I had it in .gitignore)
Some data is displayed in the truffle console

EDIT / UPDATE:
As I’m figuring out what is going on will surely update this post 
I think I’ll create a base contract and add a dummy function so that the contracts are not identical.
I think there are some “optimisations” along the way that try to preserve gas. This might be simpler, maybe, potentially.
contract OrangeCoin is ERC20PresetMinterPauserUpgradeable {
function dummyOrange() public returns(string memory) {
return "orange";
}
function initialize(string memory name, string memory symbol) public override virtual initializer {
ERC20PresetMinterPauserUpgradeable.initialize(name, symbol);
}
}
contract AppleCoin is ERC20PresetMinterPauserUpgradeable {
function dummyApple() public returns(string memory) {
return "apple";
}
function initialize(string memory name, string memory symbol) public override virtual initializer {
ERC20PresetMinterPauserUpgradeable.initialize(name, symbol);
}
}
