Yes, you can have more than one account lock out policy. This is called Fine-Grained Password policy.
You must have at least Server 2008 and a domain functional level of 2008.
These two links show you how to set this up.

Hey @Tien Ngo Thanh
There are a few options:
You can look at Managed Service Accounts (MSAs) and see if they fit your requirements. They act like computer accounts - you don't have to manually manage the passwords going forward. They cannot be locked out, but you also cannot log on interactively with a MSA.
There are a few requirements for Managed Service account - it can't be shared by multiple computers or used in server clusters, needs Server 2008 R2 etc.
There are also Group Managed Service Accounts (gMSA's) - these run on the same principle but have much better functionality, can be used on multiple computers, support more applications etc. More information can be found here:
If you cannot implement MSA or gMSA because it doesn't fit your needs, then you may have to deal with service accounts. A couple of best practices I've noted are:
• One unique account to run the service on each server
• Try to use local account rather than a global domain account
• Strong, random password
• Change the password - this will also mean you need to change it on the service/application
• Give the account least amount of permissions it requires
• Do not share the password
This will be more work your side, but at least your environment will be somewhat secure.
Hope this helps,
