isnt that multisig address ?,

No. It's a P2SH address.

P2SH addresses can have multisig as the script that was used to generate the hash, however there is no requirement that the spender use a multisig script when spending it.

and its diffucult to calculate multiple private keys rather than just one for simple address public key which starts with 1 ?

You wouldn't need to calculate multiple private keys.

You would only need to calculate a SINGLE key pair. Any private/publick key pair at all would work. You don't even need to find the original key (or keys) that were used when creating the address.

Then, you would build a script that uses the public key that you generated and a nonce value. After that, all you have to do is brute force the nonce until the hash of the script (public key + nonce) is equal to the hash used for that address. On average, it should take you approximately 2¹⁵⁹ attempts.

from 1 sha256 private key i can create WIF private key and public kay pair which is

how would i get p2sh address for something like that ?

or am i missing again something .,

does the p2sh address's private key also falls in

int range
1 - 115792089237316195423570985008687907852837564279074904382605163141518161494336

if so then how can i generate a pair ?

lets say , so far i have these
