Now this is all stuff you'll find in your amp's user manual, so you can consult that for questions of this nature, too. Here goes:
Your amp has three taps:
You only ever use one of these taps at a time.
The 8 and 4 Ohm taps have two jacks each, with the jacks being wired in parallel.
This means that for the 8 Ohm tap, you can either hook up one cab rated at 8 Ohms, or two cabs rated at 16 Ohms each, since two 16 Ohm loads in parallel equals one 8 Ohm load. Likewise, when using the 4 Ohm tap, you either plug in one cab rated at 4 Ohms or two cabs rated at 8 Ohms each.
Set your Randall to 16 Ohms. You now have two 16 Ohm cabs. Plug them into the 8 Ohm jacks. As stated above, they equal a load of 8 Ohms together.
While the amp likely will be okay if you use two differently rated cabs (long as you're running them off the same tap), you will notice a difference in volume between them, so don't do that.

Impedance is indeed different to resistance, technically, but that doesn't matter here. To simplify it for the OP:
-If you have a digital multimeter, set it to the ohms range (if it isn't auto-range).
- Plug a speaker lead into the cab.
- Place the black lead of your multimeter on the shaft part of the free end of the speaker lead.
- Place the read lead on the tip. They are indeed different electrical points, and you'll notice this because of the non-metallic ring around the tip of the cable end.
If the meter registers 3-5 ohms, you likely have a 4 ohm cab.
If it measures 6-10 ohms, you likely have an 8 ohm cab.
If it measures 13-18 ohms, you likely have a 16 ohm cab.
when in doubt, I generally go with 8, but to be safe, see if you can get your hands on a multimeter and measure the resistance of the cab - it won't be exactly 4, 8 or 16 because impedance is different to resistance, but it should still be close enough to one of those values to tell you which output to use.
is micing your amp through a PA an option?
