If the aluminum cladding is covering the building sides, can we install an air terminal on above since we cannot bond aluminum?
In 250.64(A), the aluminum conductors are allowed as along as it's not subject to be corroded.250.52(B) only refers to those things allowed or required to be used as a ground electrode. Aluminum siding is not one of the things that is mentioned as being a grounding electrode.
Air terminals are part of lightning protection systems and are mostly covered in another NFPA standard and not the NEC.
Also, if i cannot depend on using it as electrode system, but still i have to bond it to electrode systems, am i right?250.52(B) only refers to those things allowed or required to be used as a ground electrode.

I dont really understand the question. Again as Bob said, aluminum siding is not an electrode, nor required to be bonded.
I dont know what lighting protection standards say, if anything, about aluminum siding.
If it like that, how to protect the aluminium siding during lightning strikes, assuming it covers the whole building like this,
