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.

United States White House Report on Memory Safe Programming [pdf]
MISRA and Ferrocene are not really related.
MISRA is, as you say, a set of rules for writing C code, that restrict what you can do.
Ferrocene is a qualified compiler. You write any normal Rust code you want: it's still the upstream Rust compiler. There are no restrictions.
Incidentally, someone has compared what MISRA does to what Rust does: https://github.com/PolySync/misra-rust/blob/master/MISRA-Rul...
Given that they can't repeat the MISRA stuff there, it's a bit disjoined, but it sure is interesting!

Misra C++:2023 Published
A fun github repo: "what would MISRA look like applied to Rust" https://github.com/PolySync/misra-rust/blob/master/MISRA-Rul...
(They're comparing with the C version, not the C++ version...)

Ferrocene: Rust toolchain to safety-critical environments
> There are huge swathes of MISRA which forbid things which not only aren't possible in Rust or SPARK
I can't vouch for its accuracy, but https://github.com/PolySync/misra-rust

High Assurance Rust: Developing Secure and Robust Software
When it comes to MISRA C, it is interesting to note how many (a majority) of its rules do not apply or have native enforcement[1].
You might have also seen the AUTOSTAR Rust in Automotive Working Group announcement recently[2].
[1]: https://github.com/PolySync/misra-rust/blob/master/MISRA-Rul...
[2]: for some reason the announcement was removed from the "News and events" site, https://webcache.googleusercontent.com/search?q=cache%3Ahttp... but it is still available as a PDF https://www.autosar.org/fileadmin/user_upload/20220308_RustW...

AdaCore and Ferrous Systems Joining Forces to Support Rust
Rust makes quite a few things more rigorous (e.g. pairing allocations with deallocations and reference validity). It basically fulfills the job of a static analyzer baked into the language.
It's also a vastly more analyzable language (in that its syntax is reasonably unambiguous and there's no dynamic runtime in play) and it can be integrated well.
Toolchain quality (error reporting, built in testing, awareness of primitives like "libraries", etc.) is also a huge strong point.
We're reasonably confident that we can use safe Rust as is, with strong guidance on how to do unsafe Rust.
For a tangible investigation of that space, PolySync has a project that has a look at MISRA rules from a Rust perspective. https://github.com/PolySync/misra-rust/blob/master/MISRA-Rul...
Ada is a good example here: the language has not evolved something like MISRA-C (it has evolved SPARK for formal verification, but I see that differently).
What are some alternatives?
