How to deploy a solana program from a particular address or public key - node.js

Question

I've two problems here, major of all, I can't understand the difference between account address and public key of a program
The second thing is, there is a problem while deploying my solana program. I've made a deployment script...
const { Keypair } = require("#solana/web3.js");
const { Connection, LAMPORTS_PER_SOL } = require("#solana/web3.js");
const path = require('path');
const spawn = require("cross-spawn");
const fs = require('fs');
//import { Connection, LAMPORTS_PER_SOL } from "#solana/web3.js"
async function main(){
const SLASH = path.sep;
let programAuthorityKeypair = new Keypair();
this.connection = new Connection("https://api.devnet.solana.com", "confirmed");
const signature = await this.connection.requestAirdrop(programAuthorityKeypair.publicKey, LAMPORTS_PER_SOL * 5);
await this.connection.confirmTransaction(signature);
const programAuthorityKeyfileName = `target/deploy/programauthority-keypair.json`
const programAuthorityKeypairFile = path.resolve(
`${__dirname}${SLASH}${programAuthorityKeyfileName}`
);
fs.writeFileSync(
programAuthorityKeypairFile,
`[${Buffer.from(programAuthorityKeypair.secretKey.toString())}]`
);
const programKeyfileName = `target/deploy/solblog-keypair.json`
const programKeypairFile = path.resolve(
`${__dirname}${SLASH}${programKeyfileName}`
);
let programKeypair = readKeyfile(programKeypairFile);
let programId = programKeypair.publicKey.toString();
//////////////////////////////////configurations//////////////////////////////////
let method = ["deploy"] // we are deploying for the first time, using 'deploy'
spawn.sync(
"anchor",
[
...method, // we use a variable so we when we want to upgrade, we can use 'upgrade' instead
"--provider.cluster", // we want to specify the node cluster
"Devnet", // the node cluster as the Devnet
"--provider.wallet", // we need to pass in a keyfile to pay for the deployment
`${programAuthorityKeypairFile}`, // this is the keypair file we created just a moment ago
],
{ stdio: "inherit" }
)
}
main()
.then(() => process.exit(0))
.catch((error) => {
console.error(error);
process.exit(1);
});
function readKeyfile(keypairfile) {
let kf = fs.readFileSync(keypairfile)
let parsed = JSON.parse(kf.toString()) // [1,1,2,2,3,4]
kf = new Uint8Array(parsed)
const keypair = Keypair.fromSecretKey(kf)
return keypair
}
now, I'm running the script by node deploy.js but it is giving me balance insufficient error...

Recover the intermediate account's ephemeral keypair file with
`solana-keygen recover` and the following 12-word seed phrase:
===========================================================================
all orbit slim nothing learn country polar casual print help coffee gesture
===========================================================================
To resume a deploy, pass the recovered keypair as the
[BUFFER_SIGNER] to `solana program deploy` or `solana write-buffer'.
Or to recover the account's lamports, pass it as the
[BUFFER_ACCOUNT_ADDRESS] argument to `solana program close`.

Error: Account JjetRg5FHM6xpPjTT7KfrEaTBeEWxMh5Pyjo4UXw3nm has insufficient funds for spend (1.8711612 SOL) + fee (0.00135 SOL)
There was a problem deploying: Output { status: ExitStatus(unix_wait_status(256)), stdout: "", stderr: "" }.
so I'm taking the above account address JjetRg5FHM6xpPjTT7KfrEaTBeEWxMh5Pyjo4UXw3nm to solana faucet site, and airdropping 5 SOLs into that address then again I'm running the script, AND GETTING THE SAME ERROR WITH DIFFERENT ACCOUNT like...
Error: Account .
already set the env to the DEVNET.
What I'm thinking that how can I deploy the program with the same account into which I'm airdropping SOLs?
