My 70 Fleetwood has the vacuum air ride compressor which appears to work OK but it has a rhythmic squeak to it when the car is driving down the street. I only hear it when I'm out of the car but my teenage boys hear it driving. Is there a way to oil or grease the o-rings inside or is there something else I should do.

Silly question here, but are you sure it's the compressor?  Disconnect it see if the noise goes away.

If the noise is only there when driving, then I would be looking at noisy hub caps/wheel trims.

If it is there whilst sitting with the motor idling, then it could be the ALC.

Assuming the noise is originating there. They can make a clicking noise, i thought they all did unless NOT working?

So,  it’s a good sign it’s probably working ...I’d be real careful what I  introduce into it, or better resist the urge entirely.  Turn up the radio😂

You might want to change the vacuum hoses to the compressor.  If they get soft and collapse they can cause a squeaking sound.  The compressor normally runs when the engine is idling unless there is a leak.  But if the vacuum hose is collapsing it could cause the compressor to not come up to pressure.

That's a good suggestion, I will check the vacuum feed line and see if it's soft or collapsed.
