Overlapping curves' length and count

Hello,

Can you help me with how to tell the lengths of the overlapping segments in my example and also that how many curves are overlapping?


don’t worry about the numbers in the length list, they are just made up)

I need the first and 3rd (highlighted) lists and I have no idea how to do this.

Thanks for any idea!
