Dear BTRFS developers,
I would like to know if these issues are fixed or handled? Thanks.

Some bugs looks interesting and may be resolved by more checks in
tree-checker.
I'll take a look at them.
Thanks for the detailed and comprehensive report,

All these images should be addressed by the following patches now:
https://patchwork.kernel.org/patch/10503415/
https://patchwork.kernel.org/patch/10503413/
https://patchwork.kernel.org/patch/10503403/
https://patchwork.kernel.org/patch/10503147/
https://patchwork.kernel.org/patch/10503099/
Some of them may need extra cosmetic updates, but the basic fix should
not change much.
If you have any newer fuzzed image which could pass kernel mount and
cause unexpected behavior, feel free to submit them to btrfs maillist
and kernel bugzilla.
Thanks,
Qu

Sure, thanks for your efforts! So as I suppose, 199833 and 199835 are implicitly fixed by these patches as well?

Yep.
Kernel can know detect all related chunk <-> block group mapping problem
in all 6 images and exit gracefully with error message showing what's
going wrong.
You could also test using this branch:
https://github.com/adam900710/linux/tree/tree_checker_enhance
