Ubuntu Report Project for School - Questions! topic

Hey guys and gals! I am new to Ubuntu, have spent 50+ hours on it, fiddling around, researching Ubuntu from past to present for my college project. I have scoured the internet for research but - you can't really trust everything but I do trust those who have spent 20x more on it than I have. I have a few questions for everyone who's reading.

Question 1: What goodies about Ubuntu, whether it is its history, cool or strange facts, etc. That I can't find on the internet are there? In other words, I want to know everything about Ubuntu that you can't really find on Google.


Question 2: Ubuntu is an excellent desktop OS, what makes it stand out so well from other Open Source OS's?


Question 3: I can't find much on the internet about Ubuntu Phone but I am dying to know more! Please? :D


Question 4: How many people work on Ubuntu to this day? Who manages updates, etc?


Question 5: Last but not least; I am on my way to becoming a cloud computing analyst/networking, with virtualization as well, how can Ubuntu benefit the future of cloud computing and cloud network? How do deployments fair compared to other OS deployments (Sorry that was 2 questions :P)

I appreciate your time and your knowledge everyone. Thank you for answering and reading. If you have any other awesome tid-bits about Ubuntu I should write about, please let me know. I will reference you by name/username in my report (With your permission). Thank you!

Is there a apache project that I can integrate monitors of my computer and others topic

Resume:

I have a server (originally: Ubuntu 14.04.1 Desktop) with LAMP and various server things:
(site, FTP Server where users of my site can access, phpmyadmin (mysql), DX cluster (A platform where radioamateurs users can interact, and have various connections with others nodes (DX Clusters) via telnet 7300, etc...)
And I'm planning to have a Raspberry Pi to do a little of home automation like with temperature and humidity sensors and maybe later ip cameras... and more sensors, etc...

My Questions are:

Is there a apache project or other party projects where I can access via own website: memory use, disk use (e.g.: free and used percentage), etc... ?
if yes:
Is there a project where I can access via own website the above but not only of the server itself but of the raspberry pi too ?
if yes:
Is there a project where I can access via own website the above and connected sensors to the raspberry pi?
