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.

Looking for help getting started with TinyFPGA
apio is a python package you drive from the command line. I didn't know somebody had done an integration with Atom. I've installed and used apio on my phone. I wouldn't really recommend doing that, but it shows what's possible.

Learning Verilog and FPGA
I've had good experiences using Upduino 3.0 and 3.1 [0] with the IceStorm tools via apio [1]. I wrote a blog post [2] with some info on getting things set up via Linux. All you need is the Upduino board, which interfaces to your host system via USB (so no special programmer is needed).

FPGA dev board that's cheap, simple and supported by OSS toolchain
if you're more comfortable with the CLI, you should take a look at the apio project (https://github.com/FPGAwars/apio). It neatly bundles all the required tools. Regarding HDLs, I'm still learning so can't offer any good advice on that.

FPGA for beginners?
The toolchain is called Icestorm, main tool is yosys, most information will be in English. I started with this tutorials here (also in English) https://github.com/Obijuan/open-fpga-verilog-tutorial. Then I used books to learn more on the basics of cpu design in verilog (which can also found online). Obijuan is a Spanish profesor teaching digital electronics in university, he lead the development of a graphical user interface to generate verilog based on a blocks UI, which helps design circuits when you are starting, but unfortunately I believe all his videos are in Spanish, I'd suggest you give it a try even if you don't understand English, as the material available (wiki and videos) is very good. Look for "fpgawars jedi academy " and IceStudio (the tool). But in the end, I personally felt limited by the GUI tool (which was still under heavy development at the time) and went straight to code the verilog code by hand (which obviously is more flexible). Anyway I feel there are not that many pattern to know.

What's the difference between FPGA, RISC-V, Arduino?
Among your choices, FPGA is the answer. I would suggest a cheap iCE40 board like the iCESugar, to get started. Then follow tutorials targetting ice40+open stack.
