Q function vs action-value function
Is Q function synonymous to action-value function? I see it used interchangeably and also together ( ex. "Q action-value function" ).

Yes, Q-function is the term that is used for approximating Q-value which is same as the action-value function. In other words, when a function approximation is used to get the Q-value for any arbitrary state-action, that function is called Q-function.
