Some can, most can't, many mql4 functions do not exist in mql5.

There are little chance but it's not impossible, as a small subset of mql4 function are still valid in mql5. Anyway as a rule, it's necessary to make some code conversion.

Chances change.

There is no need to be harsh with people who asked a question.

OrderSend is mql5 is very different from the mql4 version, we have to wait to see how the changes described will be implemented concretely.
