OK, so you have moved all of the files in the downloads into the "files" folder in your IL2 1946 game path ...

In your IL2 1946 folder, there should be a notepad file called "filelist." Open this file. Scroll down until you see the first break in code. Right here, add the appropriate path

IE ...

3do/Cockpit/B-25J/CockpitB17G.him
3do/Cockpit/B-25J-AGun/AGunnerB17G.him
3do/Cockpit/B-25J-Bombardier/BombardierB17G.him
3do/Cockpit/B-25J-TGun/TGunnerB17G.him
3do/Cockpit/B-25J-FGun/FGunnerB17G.him

Now you should be able to fly them in game. If this does not work, I have no clue. If this doesn't work, try contacting sgwasy ...
