Can we have CU8 on one server and keep other on CU1 Exchange 2016 In DAG

We have a DAG with 3 Exchange 2016 servers. One server have been affected by ransomware and we have shutdown it.   Now we are going to rebuild the brand new server to include it.

Questions: The Exchange 2016 CU1 is installed on the servers and we are not able to find it its installer to install it on new server.  Can we install Exchange 2016 CU8 on one server in DAG and keep other servers on Exchange 2016 CU1?

Or we have to upgrade other servers as well to CU8 after installing CU8 on new server?

Please guide us how we need to proceed.
