You can import files into iCloud Drive and then share them from the iCloud Drive app (I think you need to enable it somewhere in the iCloud settings on your device to make it show up as an app). Other than that, "USB Disk" or "Documents 5" are good free file manager apps that allow you to "open in" and "share" files. If the file is in an email, you can also open it in the Mail app and then share it from there.
