Answer 1

If you want to use Azure Custom Script Extension Version 1 with Linux virtual machines, the publisher should be Microsoft.OSTCExtensions and the type should be CustomScriptForLinux. For more details, please refer to the document
For example
$resourceGroupName = ""
$storageAccountName = ""
$location = ""
$vmName = ""
$extensionName = "vm_rwq"
$fileUri = #("https://jimtestperfdiag516.blob.core.windows.net/test/config-music.sh")
$storageAccountKeys = (Get-AzStorageAccountKey -ResourceGroupName "test" -Name $storageAccountName).Value
$storageAccountKey = $storageAccountKeys[0]
$Settings = #{'fileUris' =$fileUri; "commandToExecute" = "./config-music.sh"};
$ProtectedSettings = #{"storageAccountName" = $storageAccountName; "storageAccountKey" = $storageAccountKey};
Set-AzVMExtension -ResourceGroupName $resourceGroupName -Location $location -VMName $vmName -Name $extensionName -Publisher "Microsoft.OSTCExtensions" -Type "CustomScriptForLinux" -TypeHandlerVersion "1.5" -Settings $Settings -ProtectedSettings $ProtectedSettings
Update
According to my research, Azure Custom Script Extension Version 1 does not support Red Hat operating System VM. For more details, please refer to the document
So if you want to install Custom Script Extension on Red Hat VM, we should use the new version: version 2. For further information, please refer to the article. Besides, if you want to use script to install the extension on Azure Linux VM, Azure CLI is a better way.
az vm extension set \
--resource-group myResourceGroup \
--vm-name myVM \
--name customScript \
--publisher Microsoft.Azure.Extensions \
--settings ./script-config.json \
--protected-settings ./protected-config.json
But, if you still want to use PowerShell, please refer to the following script
$resourceGroupName = ""
$storageAccountName = ""
$location = ""
$vmName = ""
$extensionName = "vm_rwq"
$fileUri = #("https://jimtestperfdiag516.blob.core.windows.net/test/config-music.sh")
$storageAccountKeys = (Get-AzStorageAccountKey -ResourceGroupName "test" -Name $storageAccountName).Value
$storageAccountKey = $storageAccountKeys[0]
$Settings = #{'fileUris' =$fileUri; "commandToExecute" = "./config-music.sh"};
$ProtectedSettings = #{"storageAccountName" = $storageAccountName; "storageAccountKey" = $storageAccountKey};
Set-AzVMExtension -ResourceGroupName $resourceGroupName -Location $location -VMName $vmName -Name $extensionName `
-Publisher "Microsoft.Azure.Extensions" -Type "CustomScript" `
-TypeHandlerVersion "2.1" -Settings $Settings -ProtectedSettings $ProtectedSettings
