One of the DC has problem and we have created a new one with different name and IP.

You can change the DNS to point to new server on Exchange TCPIP properties.

We have two DC01 & DC02 on the Exchange Server Configuration. DC02 is totally crashed and we built DC03.

However DC03 doesn't shown up, so is there something missing on the DC03 ? Do I need to set it as Global Catalog or add some roles on it ?

Exchange will only use domain controllers with the global catalog role.
Therefore add the GC role, wait about 15 - 20 minutes then restart the Exchange services. That will force Exchange to find the domain controllers and detect the new one.

You can then clean up the domain for the one that has failed.

You shouldn't be touching DNS.

The global catalog role is assigned in AD Sites and Services. It takes about 30 minutes to apply, then you should really reboot the domain controller.

Please be careful.
Use the below command to point the exchange to the new DC and restart exchange server.
Set-ExchangeServer -Identity <Exch-Sever> -StaticGlobalCatalog <fqdn>
Set-ExchangeServer -Identity <Exch-Sever> -StaticDomainController <fqdn>
