As far as zongshen rx3 and other chinese bikes are concerned, this may be an option for you but im same price tag a good japanese branded bike imported few years ago would be a very good choice..
As far as inazuma is concerned , i had experience of riding it for few hours, its a very good bike, awesome road grip, best pick in its class, much better build quality then chinese and other japanese trails etc too.. As you are a beginner in this field so you obviously dont need a trail enduro type thing..
The other factor is you would get a few thousands km used inazuma for a almost half of the price, which makes it a a worthy purchase. its a simple machine with great looks and ride.
now i come to the ybr type 125 class bike, its a good looking bike, better than cg125 etc, but if you want something more good, go for a gs150 suzuki, as far as beginner bike is concerned, in UK,US lady riders start riding above 500cc machine initially which they upgrade with 6 months or an year
