I am currently completing my high school in India, studying commerce(eco, statistics, business studies, accountancy) with IP(informatic practice which includes programming such as Java and MySQL) do i have any chance of becoming a computer engineer via these background if I am going to study in USA for my undergrad if possible what should I take as minors and majors and what does minors and majors actually mean?
A Major is the field in which a student focuses during the course of his/her degree. If you are a HS student, then you would apply for an Undergraduate major which could take anywhere from 3-5 years to complete and you receive a Bachelor’s degree (BA/BS).
A Minor is a secondary concentration of courses that often complements the Major. You can fulfill these requirements simultaneously with your 4 year Bachelor’s degree.
In general, US colleges/universities want HS students to have a well-rounded curriculum which usually includes 4 years of English, 3-4 years of Science (Physics/Chemistry/Biology), 2-4 years of Foreign Language, 2-3 years History/Social Sciences and usually 1 year of Arts/Humanities.
Since you will be an International applicant, you will need to look up the International admission requirements needed for each university/college of interest. The classes you have taken will be beneficial in your pursuit of a Computer Engineering degree at a US university however, you would still need to meet other course criteria as mentioned above for each school. You will also need SAT and/or ACT tests, TOEFL (English competency test), possible letters of recommendation etc…

thank you so much this really helped
The commerce track doesn’t lend itself well to computer engineering since it doesn’t sound like you took calculus or physics.
However you may have a shot as a CS major at colleges that don’t admit by major (look up Marist, Butler, Drake, St Lawrence, Rhodes, Susquehanna, Allegheny, Millsaps) or if you apply for IST (look up “Penn state IST” or “UCincinnati IST” for instance) or for a CS BA (look up “UMN CLA CS”). These tracks or college value students with more interests than stem (you could indicate interest in economics in addition to CS for instance.)

should I give act or sat?
Try a practice test of both, compare results, and pick the one you do best at. 
Note that in the US, Teachers give exams, and students take them.
