This is the ulog file of my latest flight. Can somebody explain me what’s wrong in this flight? Please help me to find the problem.

Looks like thrust loss on Motor 4. That is a very old version of firmware you are using. I suggest you update to current Stable and start fresh.

I would also be more contented if you could suggest me how did you evaluate based on the log files, and again how to analyze logs efficiently and read from it and evaluate the data

Graph the RCout’s. Clearly Motor 4 was commanded to max indicating thrust loss.

Read the tuning and log analysis wikis. How to analyze logs is a learned process that can’t be summarized in a post.
