Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

An Apologia of Lazy Evaluation
Usually the arguments are a) it provides runtime access to the source (which for example is useful in R), b) runtime introspection is easier to understand (for the proponents) and c) macros are too static (they want more flexibility at runtime). For example authors of the REDUCE computer algebra system disliked Common Lisp for the lack of FEXPRs and that's why they stayed away from it: https://reduce-algebra.sourceforge.io/ .

No, see above.

Maxima: A computer algebra system written in Common Lisp
Reduce is another lisp based computer algebra system from the prehistoric times, now open sourced.

I paid money for a Reduce release for RISCOS back in the last ice age. I recollect having to register my licence with the Rand Corporation for some reason.

A Modern Fortran Scientific Programming Ecosystem
I idly wonder how these compare to the arbitrary-precision implementations in REDUCE (https://github.com/reduce-algebra/reduce-algebra/blob/master...) - written mostly by me, 30 years ago in the unusual, Lisp-based but largely procedural, language of REDUCE. Can't remember much about the subject now.
The citations in the Julia source file are certainly newer - Abramowitz and Stegun was basically all I had.
I think the REDUCE functions were considered quite fast (for higher precision) at the time, but it was certainly true that they weren't tested as thoroughly as would be the norm now.

Trying to understand the difference between GNU ELPA and NonGNU ELPA. Plz help.
MELPA is definitely the biggest package archive, probably mostly on account of the lower barrier to entry compared to GNU ELPA (maybe the difference would have been less pronounced if NonGNU ELPA had been there from the beginning, but one can only speculate). MELPA has its own requirements for packages, but indeed copyright assignment to the FSF is not one of them.

is there like a resource where I can learn how to create an elisp project
I would suggest to start at reading the manual first. Then I would recommend reading the Melpa guidance, even if you do not plan to contribute your package to Melpa, since it contains very useful info about linting, writing your code etc.

melpa.org blacklisted ?
The mxtoolbox link checks for SMTP blacklisting.. People won't be able to send mail from host with the IP address 178.128.185.1(which is the melpa.org webserver, not their mailserver, so everything's fine there).

Elisp project best practices
Observe that package.el compile files when they are installed, and they are not compiled in any particular order (actually whatever directory-files returns, which is what OS returns). So if you have multiple files that depend on each other, it is something to think of. There are also some guidelines on how to structure your project on Melpa.
What are some alternatives?
maxima-client - Maxima client
straight.el - 🍀 Next-generation, purely functional package manager for the Emacs hacker.
symengine - SymEngine is a fast symbolic manipulation library, written in C++
elpa-mirror - Create local emacs package repository. 15 seconds to install 115 packages.
SIunits - A Scheme function to format physical quantities according to SI conventions in TeXmacs
use-package - A use-package declaration for simplifying your .emacs
Bessels.jl - Bessel functions for real arguments and orders
