The main other known examples ares Julia and Ada (which is in honor of a real person).
The Tiobe index of top-100 languages doesn't have even one female name apart from the above and a language called Alice -- so, like, 3 in 100. In the past there was also Miranda and a couple others. Nowhere near the 5% of names.
For the complaint to even be remotely justifiable female names should have been around 30% or more of programming language names...
There are plenty of tools without female names. More than tools with female names (off the top of my head)
In those languages almost half of nouns are gendered, that doesn't make it a "female's name".

> "Influenced by Perl, Matz wanted to use a jewel name for his new language, so he named Ruby after a colleague's birthstone."
> "Later, he realized that Ruby comes right after Perl in several situations. In birthstones, pearl is June, ruby is July. When measuring font sizes, pearl is 5pt, ruby is 5.5pt. He thought Ruby was a good name for a programming language newer (and hopefully better) than Perl."
They exist, I'm not sure how the ratios stack up. I suspect both are outnumbered by acronyms. Some projects get named after their partners or children.
Depending on the license, you might fork the whole project and change the name to a genderless name. Keep the project in synch with upstream, only change the name in code and docs with sed.
