I'm using iPhone and MacBook. Both there are a default English-English dictionary, which is convenient.
However, I'd prefer a French-English dictionary, while I'm learning French on iPhone or Mac.
Is there a way to change the default dictionary on iPhone or Mac, to a French-English one?
Whichever dictionaries you enable in the Dictionary app's preferences will be available in the dictionary popover. You could either change these whenever you want to switch, or perhaps just leave both languages enabled all the time.
Yes, just go to the Preferences for the Dictionary app. There's a list there of all the possible dictionaries, which you can then drag to be in any order you like.

Assuming you are talking about the reference dictionary for looking up the meanings of words (NOT spellchecking/autocorrection), you cannot modify that on an iOS device. But in OS X you can add other modules. This page provides some info:
