First of all the images you posted you cant make anything out what you got there. Secondly you should contact a local Architect when doing something like this, not only for structural reasons, but window design as well. He will layout window detail based on the window sizes available from a certain manufacturer or you can take his drawings which indicate opening detail to a place who sells windows, and they have catalogs of window combinations and sizes to make it work with what you have.

Hello Mr. Sanjeev. Certain things definitely call out for professional help. I would recommend you to hire a professional on this very matter who can provide you with custom solution, rather than getting confused over the comments you gonna receive for this post.
