Question

what is the allowed minimum target iOS version and device platform for a new iPhone App to get uploaded on AppStore

Answer 1

Apple support iOS 4.3 see Setting Deployment Info. But support 64-Bit Binary minimum deployment target of iOS 5.1.1

Apple has officially announced apps need to be compiled with Xcode5 starting February 1, 2014:

So you must have Xcode5 for submission app in to app store. And in to xCode5 we can not define device platform like(iPhone4,iPhone4s,iPhone5,iPhone5s.. etc.) we can set deployment Target so you can setting minimum deployment target is 6.0 if you want to less then 6.0 and if you are not find that Option like Bellow image you can directly type in to Deployment Target filed.
