This is a thinker.... (no paint on all 3 brushes)

An old small paint can will do ( cleaned of course ), or you can use a glass container if you have one big enough to hold everything in it. Whatever you use, be sure to put a top on it as lacquer thinner can evaporate pretty quickly. A couple of hours of soaking should do the trick. BE SURE to remove the air valve or it will seize up from swelling. Also be sure to have adequate ventilation and wear gloves if you can. HTH.

What kind of metal container would you suggest that would work for soaking the brushes in Lacquer thinner?

16 psi is way too low for a siphon-feed airbrush.

Depends on the airbrush.  I can go as low as 8psi with my Badger 150S and spray as long as the paint's thin enough.

Cowboy, I had a similar thing happen to me after using some old enamels.  I had air, straight thinner and double checked the re-assembly twice.  What I ended up doing is taking everything apart, down to the barest parts and soaking everything, including the body, over-night in Polly-S, E-Z Stripper.  After cleaning the stripper off and putting it back togethor, it worked like a charm.  I think that there was some un-see-able residue that was broken free.  I imagine that any stripper will work, just keep it outdoors if possible.

Since you seem to have looked at every thing, think I would go for a kill or cure scheme.  Load up with thinner, crank the air up to 40 or 45 psi and see what happens.

Try a simple fix first. Rub some wax on the needle from the taper down, then on the threads and base of the tip to ensure that an air tight seal is made. If there is a leak from the paint feed tube to the end of the tip, it won't work.

It sounds to me that the "good cleaning" may have removed some old paint build up that acted as a seal before. You can use regular candle wax for a test, good quality bees wax is better. Doing this, my 13 year old Badger 100F still acts like it was new. And no I don't buy new parts all the time. 3rd needle and head assembly, second bearing (first one I screwed up and damaged 2 years ago).

WOW all 3 won't spray!
Ok, we have to look at common variables...
Is there air getting to the AB's? Yes
Were all 3 AB's put back together correctly after cleaning? Definately
Are you sure the AB's will/were spraying air before adding the paint? Yes
Was the paint thinned enough? It's Krylon, it's very thin out of the can
Is 16 psi enough to blow the paint out? More than enough
Did the solvent in the paint eat any seals in the AB's? Maybe, I need to go pick some up anyway, so, maybe that will fix it.

Disconnect the AB from the airhose and blast some air.
Dismantle and clean an AB, looking for any problems.
Try again.

already did.

It may be the seals, so I'll check that.

I'm going to ask a really silly question here.  What happens if you just try to pass thinner through it?  Does THAT even come out?  How about back-flushing?

hmmm none of the three spraying sounds odd...I'd definitely check the hose without a brush on it, try taking the head off of one and see if air comes out when you push the trigger.    Eliott's recommendation might be a good place to start if that doesn't work...

--edit--

also check the pickup tubes on your color cups.. I've had those clog once when I was cleaning them with pipe cleaners and some of the threads and come off inside the tube and paint had collected on them...

Check your paint thinning ratios and if that's good, make sure the breather hole in your jar adapter is open. If none of this works, you may end up having to soak the brushes in lacquer thinner (except for the air valve). Let us know how this turns out.
