Can I Update these log4j to an upper version like 2.16?

No, it could well break Bitbucket, and it would render you unsupported.

I'm assuming this is in response to the CVE - see https://community.atlassian.com/t5/Trust-Security-articles/Atlassian-s-Response-to-Log4j-CVE-2021-44228 for the guidance on what to do.

what will happen if we delete these log4j files?

Bitbucket will stop working.

How to upgrade log4j files to the 2.16 version?

You do not.  You will need to upgrade your bitbucket

In bamboo latest version also uses log4j 2.9.0 file, how to remediate this?

Make sure none of the users can set up plans that could throw malicious code into the log file.

Hi Nic - How to monitor these new plans? What is the solution for the long-term fix?
