Earlier I used to copy mail using create Document where email formatting was not maintained. In order to overcome this, I used a script by which I could access the retained properties of mail. But now the issue is that it takes too much time copy mail from one NSF to another.

Yes, you can copy the emails from an NSF file with another using the NSF Merge Tool. This utility is too fast to join & combine NSF Files. It just takes 15 minutes to move 650 MB of NSF to another having 5000 emails.

I tried to move emails, contacts, calendar, notes & task from one NSF file to another. But I found various duplicate email in the latter one. How can I avoid the issue of duplicasy using NSF Merge tool

Yes, you can move emails, contacts, calendar, notes & task from one NSF to another using the SysTools NSF Merge software which provide you the "Remove Duplicate" option. By checking this option you will get the new merged NSF filedevoid of any duplicate items

How to know which NSF files are password protected or not? I have a folder in which there are multiple NSF files & I am unaware about the ones that are and are not password protected. If I try to merge a set of password protected NSF files with unprotected NSF files, would I encounter any error message?

No, the software does not support password protected NSF file for merging. The NSF Merge Tool simply skips the password protected NSF files & merges the rest of the files.

I have merged my NSF files without emptying the trash folder. However, after merging, I feel like removing them all at once. Is it possible?

Yes, using NSF Merge tooll, the NSF file size can be optimized. The software features an option to exclude deleted items. After doing that, you will notice that your NSF file has comparatively shrunk in size.

I joined a new workplace where there are around 200 employees. They have this custom of introducing new employees to all the office members through mail. I do not want to type all the email IDs manually. If I use the address book (Names.nsf) of my colleague, how can I combine my personal contacts with the names.nsf file without overwriting it?

Yes, it is possible to merge two address book without overwriting both, by using SysTools NSF Merge tool.
This is because your contacts are stored separately in Domino Server as names.nsf. Browse the Names.nsf files on the software and all the Lotus Notes contacts will be listed in a single Address book.
Yes, in offline mode you can copy the NSF file of Domino server to your target PC and thereby merge two NSF Files together. For the software both files are NSF files so there will be no issue in merging these two files.
