Is there a good soul out there that can help me?
You're having a typical npm EACCES permission issue. It has to do with your user not having permissions to modify the directory where npm is trying to store global packages. It can be very annoying. You should look here and see which solution fits you best: https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally
You can fix it with,
sudo npm install --unsafe-perm -g polymer-cli
Unsafe-perm flag is set to true to suppress User Identifier/ Group Identifier switching when running package scripts.The flag is explicitly set to false to prevent non-root user from installing packages.
You can also try to change ownership of node_modules,
To change ownership to current user as group -
sudo chown -R root: <YOUR_USERNAME>/usr/local/lib/node_modules/
sudo chmod -R 775 /usr/local/lib/node_modules/
And never use sudo for npm related query.

Some of the nodeJS modules are written in c++, and need to be compiled when being installed. This process requires python2 to be installed. Now, most Macs actually have python2 installed by default, but 'python' might not be on your executables path yet.
On a Mac, the python application is typically located at /System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7. If there is no 'Python.framework' folder in /System/Library/Frameworks/ you will need to install python. If it is there, then simply symlink the previously mentioned python2.7 executable in /usr/bin. Also ensure that /usr/bin is present on your executable path by typing echo $PATH on your terminal.
To create a symlink run:
cd /usr/bin
sudo ln -s /path/to/original/python python
When i run my first react app using npm start command some error is displayed. Please some one help me to resolve this issue.

It seems there is an error in a library.
I appreciate if someone tells me a solution for it.
As the developer said, He has no plans in the short or medium term to continue development, so you could consider use netcdfjs, that it's a javascript library that allows to read NetCDF v3 files. Because it's a NodeJS package you can run it server side, and for regular size files you can read it online, here you have an example.

Is there a way I can solve this issue? The other questions on SO seem to have fixed the issue by trying sudo but not for me.
Try to use an express command with a full path: /Users/[name]/.npm/bin/express or sudo /Users/[name]/.npm/bin/express.
Looks like PATH variable wasn't set after installation. (https://en.wikipedia.org/wiki/PATH_(variable))
