Questions about the transcripts sented to the college admission as a student who had gone to 3 countries for high school experiences!

Background: I have been studied in China since my birth to grade 9. Then I went to British Columbia, Canada for grade 10. After that, I transferred to a boarding school in Florida and repeated grade 10. I didn’t really appreciate and enjoy the studying atmosphere in Canada.
(I am new to the admission process and I don’t really know how will they treat my transcripts and count my GPA)
Questions: 1. Will my grade 9 transcript(in China) be sent to the admission?
2. Will my grade 10 transcript in Canada be sent?
3. If yes, since the grading system is different, how it will be viewed?
4.It was mandatory to take PE and CLE(Career Life Education) in Canada and I got 2 Bs on those 2 courses. Will those courses be counted in GPA or only the credits?
5. If I took English 10 in Canada and take English 10 again in America. Will both of the grades be counted?
Thank you all for taking the time to view this and it will be great if you can answer some of my questions.
