Answer 1

If you're studying French, those sentences shouldn't be too hard to write in French! ;-)
However,
Je m'appelle. J'étudie dans la classe XII c de l'école Joseph Matriculation. Mon professeur/ mon enseignante s'appelle Mlle Lilly Therara. J'étudie les sujets/les matières comme la commerce, les comptes, l'économie et, bien sûr, le français. Il y a 38 étudiants/élèves dans ma classe.
I am sorry, I don't know exactly what you mean by 'school people leader'. In the US we have student council presidents, in France there is a student (or some students?) who sits on a council with the faculty and administration, and of course those types of jobs would be expressed differently.

I have tranlated whatever I could based on what youve written..
