Hey Anshita
First of all I want to tell you that if you wantt o do graduation and persue post graduation after this then please dont tak egeneral bcom and only go for bcom honours , no matter which college provides it. As for your chances in admission to the mentioned colleges I am sorry but Narsee Monjee has a cutoff above 91.8% for general category and St Xaviers too is expected to have a cutoff above 91% for non christians. HR also has a cutoff above 90% and Mithibai and RA Poddar will have no less than 90% as they are premiere colleges. Moreover this year most cbse as well as isc students have got higher than usual marks hence the cutoff is only expected to increase.
