What's the difference between this and https://github.com/SonarSource/eslint-plugin-sonarjs

Are these 2 separate plugins?

There are some rules in SonarJS unavailable in eslint-plugin-sonarjs, so I extract rules in SonarJS to this project.

Take sonar/deprecation as example.

And you can see the rules list at https://github.com/rx-ts/eslint-plugin-sonar#rule-list and https://github.com/SonarSource/eslint-plugin-sonarjs#rules

Does this work well with Typescript projects? I already have eslint rules applied with a few TS projects, I wanted to know if there will be conflicts.

It uses typescript inside as peer dependency, so it works well with TypeScript of course.

I wanted to know if there will be conflicts.

I think you should try it by yourself, I use it in my own and company projects, and it works well without conflict. And if you just find conflicts, you can easily disable one of the rules from it or other eslint plugins.

Cool but there seems to be some rules that are in sonarjs and not in this repo like for example https://github.com/SonarSource/eslint-plugin-sonarjs/blob/master/docs/rules/cognitive-complexity.md. I didn't see that mentioned in your README.md.

SonarJS and eslint-plugin-sonarjs are different, this plugin extracts rules from SonarJS which could be considered as additional rules.

So that short answer is you may want them both.
