Whoa! Your shits tubeless!
You need to really think about your plan and technique then.
Possibly what up is first getting them cleaner.

Oh wait… first up is the good wheels/tires need to be aired up and checked for functionality.
Then proceed with the clapped out ones.
Can you find replacement tires?
You’re going to need a proper air compressor to seat the tires. A tire shop will help you out.
The “good” wheels need more scrubbing. Just worry about getting the tire mating surface smooth.
You might need to sand any rough spots off the bead of the tire also so it gets a good seal.
You need A schraeder tool, and some new schrader valves.
You can dump air with a regular fitting for air…
this one here:
Fwiw, this works for car/motorcycle tubeless wheels also, you just need a thicker hose, like 3/8" to flow enough air.
Take the schraeder valve out, and just push the female air fitting onto the valve stem to fill it up.
When it’s inflated, pull it off and quickly put the valve core in with your tool.
