ok so I did some measures I couldn't be so precise because I am alone... I am more tall legs skinny body long arms my uperbody is short compared to others.

So after reading all your comments I should go more with the red bike ? thank you all really make me fell more confident

Edit: Forgot to ask xD, would be possible to upgrade a bike like this ? I am not so sure for example with the breaks and the gear system, would be possible for example to modernize such a bike ?? like change the breaks leaver and take out the actual gear shift and put one modern break and gear shift lever set ?? Thanks again
