Hey there,
Welcome to the forum! Also, thanks for sharing all that information - that makes this a lot easier!
As for your short listing exercise...I think it has a ways to go still

Overall, you have an interesting profile and I like it. Your work experience most assuredly counts if you were in a self created start up. Depending on how successful you were or what scope of responsibilities you had, it could trump some of your peers. Don't discount that for a moment. And that's not all you do - you're involved in a host of other positions and activities! I'm not going to spend a lot of time telling you you're in a good spot. You are. Your GPA is a little low but it isn't the end of the world.
The unfortunate part, however, is my answer to your question. You probably shouldn't be looking to R1 deadlines. If you take your GMAT in early September, that doesn't give you nearly enough time to set your strategy and execute applications. You're better off applying R2 (yes, I know, everyone says R1 but that only applies if you're in the position to do so). Don't rush for R1 and shoot yourself in the foot because you rushed!
For the goals you have and the things you're interested in, there are a host of schools you could apply to. The ones you've listed are all vastly different in terms of curriculum, culture, networks, etc.
Here's what it comes down to - take your GMATs in September and see how you do. We could assume you get a 700+ but it does no good if you don't get that or you far exceed it. This is a purely hypothetical discussion at this point. Once you have that in hand (and you're happy with it), then get your nose to the grindstone. Finalize your school list, establish your strategies for those schools, and get moving on those applications!
I wish I could give you a better answer but without your GMAT and as an Indian applicant, there isn't much more we can do with school selection at this point.
If you want to chat more though, either reply here or reach out to me privately. I'm happy to help you talk through this over the next couple of months!
Cheers,
Bhavik
