Generate a single shapefile from various intersection agreements

I have five vector files wherein I want to determine the spatial agreements among them using intersect. Here is my illustration. (Actually these are forest shapefiles from five different forest maps)

 

A = vector_file_1.shp
B
= vector_file_2.shp
C
= vector_file_3.shp
D
= vector_file_4.shp
E
= vector_file_5.shp

 

So that I will have a set of spatial agreement from 2/5, 3/5, 4/5 to 5/5. For example:

1)   2/5 = AB, AC, AD, AE, BC, BD, BE, CD, CE
2)   3/5 = ABC, ABD, ABE, ACD, ADE, ACE, BCE, BCD, BDE, CDE
3)   4/5 = ABCD, ABCE, BCDE, ACDE
4)   5/5 = ABCD

 

My question is what geoprocessing technique will I use to generate a single shapefile from each agreement above (except item # 4), supposing I've done the intersection combinations for agreement items 1-3? Will I use intersection again, union or other technique?

(My professor told me to just add a field and put a number code on that field, for each shapefile, unfortunately I forgot the next process he mentioned.)
