Have you read through the FAQ thread here first?
http://www.futeko.com/newforum/index.php?topic=1517.0

A lot of your questions are already covered in detail and also link to other threads. 
It is usually best to search and find a specific thread with any question not covered in the FAQ and ask there. 
We all try to help new owners where we can 

Many thanks Phil181,  but believe it or not, FAQ's was one of my first destinations where to read about, but as you can see if you look into them, those are mainly ways to action different features, rather than explanations themselves about what the things are.

Couldn't find clearly information about what Samba is, or what it is important for?
Same with Wrapper, it does requires login... not even sure where to get it from and with which purpose?
Is there a way to customize my box main menu (removing facebook, skype, or make it more Android handset menu alike) easily? Or might I need to learn to root it... I have the latest sold version as I've received the box literally two days ago.
On top of this, there are few apps on within the preinstalled ones which I have never seen before and it will be more than welcome a guide through explaining what are those used for and how to use them?

Samba is the technical name for Windows networking. It's the most commonly used networking standard.

Wrapper is pre-installed. If you are using a password protected Samba share you'll need to enter share details in wrapper app, which can be found at Home - My Apps - Wrapper. In Kodi you can select whether to play media with wrapper or Kodi internal player by navigating to media, pressing remote menu key and selecting wither 'Wrapper' or 'VideoPlayer'.

Apps on home screen tiles can be swapped by navigating to tile and pressing remote menu key. It will take you to My Apps page where you can select an alternative app. On Android 7 firmware the launcher (the home screen app) cannot be changed, on the Android 5.1 firmwares it can.

Which apps exactly do you want a guide for? Most apps have their own help pages, usually online.

Thanks a lot, I will take it from here to start my research.
I will try my best to make sure I'm not asking for redundant or already published information in the forum

Settings - More - Apps - at top right enable 'show system' - Launcher_3D - Storage - Clear Data

That will reset launcher apps to default.
