I don't know if it's a strict definition, but in general:

- function generator - usually generates more then just sine waves, at
least in addition to sine some square waves. Often others (ramps,
triangles), and also often modulation of those waves (i.e. FM, AM, PWM).
May generate into the RF region, may not.

- RF generator - usually only generates sine waves, but perhaps offers
more modulation choices. At the most basic I'd expect at least AM and FM
modulation. Obviously generates in the RF region, and usually doesn't do
anything for lower frequencies (i.e. 20kHz).
