You can save the OBJ files as a prop. Make sure you have the item selected. In your library, click on the props icon. Then click on the plus at the bottom left. You'll get a popup window for a name. Enter that and click ok. It will now be in your library. Poser will autogenerate a thumbnail of what is visible in your current camera so You might want to focus your camera on the prop you're saving. You can also make your own thumbnail with any png that you name the same thing as the prop.

For the rar files, you need to put them into a runtime.

cr2 goes into the characters
pz2 goes into Poses
fc2 goes into faces
hr2 goes into hair
hd2 goes into hands
pp2 goes into props
lt2 is for lights
cm2 is cameras
mt5 and mc6 are both materials
pz3 is scenes

Each file should have a corresponding png thumbnail that goes in the same folder.

Texture files go in the texture folder. I strongly recommend keeping the file structure that it was compressed with, such as runtimes/textures/redphantom/prop/texture to help Poser find it and avoid overwriting other textures with the same name.

obj files would go into the geometry folder. And again, I recommend keeping the file structure.

if you find rsr files, those are an old format for thumbnails. Poser 11 won't read those. If there is also a png thumbnail, you can just delete the rsr. If not, you'll need a file to convert them.  https://www.renderosity.com/freestuff/items/57197/rsr-to-png-converter will work.

If you add something to your runtime while poser is running, you might need to hit the refresh button for it to show up. You can find it as a circle arrow at the end of the folder name. There's also a double circle arrow in the lower right corner of the library that will refresh the whole library. That might take a few minutes depending on the size of your library.
