I am looking for an easy way to pump water uphill out of a barrel. Feel free to suggest other methods, but in particular I am wondering about the following:
Can I use a siphon like this as a manual water pump?
The product description at this link says I can use it or air; would it be practical to use for water?
I don't see any problem with installing it horizontally on the run between the two sinks. You'll probably need a new slip nut (the part that goes on top of the trap) but otherwise it can probably connect into the existing union that's there now. Just keep the piece that goes to the RO on the top (facing up).
A piston pump compared to a plunger pump, from Wikipedia. The parts you specified from your picture are piston pumps.
A piston pump is a type of positive displacement pump where the high-pressure seal reciprocates with the piston.1 Piston pumps can be used to move liquids or compress gases.

That's not going to get you very far with actually pumping water uphill. It can get a drain/hose started -- like an aquarium siphon kit -- but if you need the water to exit the hose at a level above the water level within the barrel, a better solution would be an inexpensive submersible pump.
You can find submersible pumps of varying sizes at major home improvement stores, online e.g. amazon, at large landscape or swimming pool suppliers, etc. I have a really small (~$20) one that would be good for the barrel situation; I've also used it as a temporary laundry pump and to drain rain water from swimming pool covers. I just put on a 1/2" ID clear PVC hose and plug it in.
