Full wipes are usually needed whenever you change ROM, whether it's before restoring a backup, or before flashing a new one.
Does it work if you move your TWRP backup off the device, do a full wipe, then put it back and restore?

You cannot restore a ROM of a different version of android than the one you are running.

It mean that i should first flash 4.0.3 than restore the stock rom

check this "funbook gizmolord" website... goggle that words and check the website...
The way you're stating things is off, so I'm assuming you mean you created a Nandroid before flashing the new Rom? If so then yes, just wipe data, wipe cache, format and remount system and then re-flash the stock Rom by whatever method your devices uses.

[Q] Stock boot.img for Villec2

Do i need to flash a stock boot.img when restoring a backup from TWRP?
My experience points to yes because I tried and it never got to boot animation after nandroid restore. Not 100% sure though.

Well if you think about it technically... If your backup is a custom rom and you restore it you have to flash its kernel, so since the backup is like a custom rom only backupped so you will have to flash its kernel too

Backup EFS partition with stock recovery?

I have just rooted my n5, and for now I want to stay stock.
I want to backup my efs partition, just in case. Is it possible to do so using the stock recovery, or make a full nandroid?
You will need custom recovery and then can do either a full backup or just the EFS. I know for certain that TWRP gives you the options.

I know I can do it with TWRP but is dit possible without custom recovery ?

Details of a rom from Nandriod Backup

Hello
All XDA members
I have a problem that made me raise a question an that is an we know the name of a rom from a nanriod backup either on PC or on Andriod.??
Ideally PC would be good !!
Thanks
Most ( not all) recovery apps let you name the file. Are you asking how to find the file? If so, it likely is in a folder named backups. You can move the file to your pc and keep it there if you are out of storage space.

Sorry if I wasn't clear please consider the following situation :
I have around 12 backups of different roms and I dont want to restore each n every backup for sake of simple file or simple thing. So any tool which can read the name of Rom? Probably the buildprop or about phone info will help

Well, if you gave a single boot system, your recovery should "see" all of those files. If so, you can usb them or copy to a sd card and move them. Just move them back when you need to.

Can someone explain nandroid backup to me? Does it mean I can make a backup my current rom and save it? Sorry for the dumb question.
Yep

Simply,it is a backup of your OS and settings. It is extremely valuable if you flash a new ROM that doesn't/won't function. Then, you can use your recovery to, well, recover your previous WORKING OS.
When/if you begin to flash new ROMs (and other tools that may corrupt your OS) you should always.first.backup.your.files.
Can I assume I would need to wipe data/factory reset, etc. before I restore the backup?

So, that depends on what your starting config is, what you upgraded to.
For instance, if you are stock and flash a ROM using the stock recovery, then likely yes. You should and you would use the stock bootloader to wipe with.
If you have loaded a new recovery (TWRP, CWM) then read(!) the instructions on the developers page. My example is that on my tablet, once I upgraded to TWRP, I SHOULD NOT use the factory wipe option as that would wipe both TWRP and the backup files. That would cause lots of problems so, don't assume.
Typically, you do need to data/reset/wipe prior to flashing a new or recovering to an old ROM, just be careful what/how you do it.
I have a CWM recovery installed and installed custom Rome before. I have always redid everything again. So a backup would save me a lot of time.

Then, unless the ROM developer states otherwise, you should make backups, wipe data, install ROMs and recover your device using the Nandroid backup.
You likely shouldn't use the "factory" wipe data as that would cause issues.
