Can H-1B transfer happen in such case from company B? If yes then if this transfer is approved but previous H1b extension is not approved which is from company B will it impact my status in US? Can I work for company B still? Will there be any chance that I have to go to India and come back with stamped visa ?
Yes you can. You can join company B but if the case is denied you will have to go outside the USA for visa stamping. FAQ in detail...
