How do I implement my own trained neural network on the PYNQ-Z2?
Do I have to create my own overlay? If yes, how do I start doing that? If no, then how do I know whether the overlays on git is suitable for my network?
(I have no prior knowledge on FPGA)
Have you looked at any of the NN projects & research here: PYNQ - Python productivity for Zynq - Community?
Find one that best fits your goal and modify it to suit your needs. I expect that you will need to customize the code to suit your specific needs. But that really depends on the details of your goals.
If you need help creating your own overlay, there are step-by-step instructions on the Pynq site and numerous videos on YouTube. I found this one to be a very good intro: - YouTube
In order to recreate the hardware designs for GitHub - Xilinx/BNN-PYNQ: Quantized Neural Networks (QNNs) on PYNQ , it says I need a Linux machine but will a Windows 10 Home be enough?
The framework/scripts are based on Linux. You may be abel to use a Virtual Machine on your WIndows laptop.

I am having problems with the hardware design rebuilt.
After entering ./make-hw.sh cnvW1A1 pynqZ1-Z2 a on a terminal in Ubuntu 16.04.03 LTS,
I got the following CRITICAL WARNING:

I was wondering if you are using 2018.2 vivado to open a 2018.3 project?
Woops. The “Hardware design rebuild” section on the BNN git said the terminal commands were tested with 2018.2 so I assumed that the project was in 2018.2 so I installed the 2018.2 Vivado WebPack. Thanks for pointing it out.
