OK.... but there is nothing simple about what you are asking for.
In my opinion, to do what you want, one needs a full natal analysis of each individual chart which has too in clude the major strugles of the present, how they deal with change and how it deals with them and full analysis of their cognitive structures, as well as their fences in life and their open ended growth.
Taking that for each we then need to look at both the struggles and the growth areas as shown in the synastry.
In the real world what you are asking for would cost many hundreds of dollars, due to the time required to compile it.
On a forum like this, you might get maybe 5% of that free. No one here is going to provide 6 or seven hours or more of free astrology analsysis---even if they actually knew how to do it.
