Follow the below steps-
1. Create the mapping as if there is only single source and target.
2. Now create an additional file on the server which will list the multiple source file names along with their paths.
3. Specify the path and name of this file in the "Source File" under session properties. 
4. Now the most important thing - Set "Source Filetype" as "indirect" under session properties.

If the lookup source is same for all the lookups and if we are returning different columns for calculations then it is better to use unconnected lookup with expression instead of using connected lookup.

You can use Normalizer t/f to achieve the desired output. There is an "Occur" option in Normalizer in which you can mention the no of times you want to load the same source data into target.
