Get all "type_parameter" about several "RFA_files"

I want to get all “type_parameter” about each “RFA_file”.
As attached file “case_01”,I could get the “type_parameter” succesfully about only one “RFA_file”.

But I couldn’t get “type_parameter” in the case of several “RFA_files” which were selected previously as attached file “case_02”.

If possible, would you give me good advice to solve the above error problem of attached file “case_02”?
For example,good packege,good node・・・・

Like below, you can use in the dummy Revit file.
