What is the public key of actual address that i mentioned in OP which is the address 3BJKWL5ipkVe2bjkRSt6ZNbVWQaRrEFjMs ?

That address is a multi-signature address and for generating that, you need all the three public keys.

In a m of n multi-signature address, there are n private keys and n public keys and you need m of the private keys to spend fund from that.
The address in question is 2 of 3 multi-signature. So, there are 3 public keys and 3 private keys and for spending fund from it, 2 of private keys are required.

Got it. Thanks for the explanation
So basically using multi-Sig cold wallet on airgapped machine provides the ultimate security?
I was thinking what if someone generate the same private key as my address in case of single address (which is very very unlikely) but using multi-sig makes this impossible,yes?
If an address is multi sig of say 3 address then attacker has to find 3 private keys correct?
Also bitcoin send to individual address which generate multi-Sig can also be spent individually right?
