@katelynk005 Some sims appear in the Create a Sim bin for you to further edit in CAS, not in the Edit Town bin where you can just place them in houses. If the missing sims aren't there either, try installing them into a clean game folder. Pull your entire Sims 3 game folder out of Documents\Electronic Arts (putting it on your desktop is fine), and open the launcher to spawn a new folder.
Download just one of the sims and install, and then download and install the sim's cc if necessary. Then check your game to see whether that sim shows up. If so, the problem is likely a corrupt file in your old game folder. Let me know, and I'll write out how to proceed from there. If the sim still doesn't show up, please PM me the link to that sim as well as any associated cc. And let me know what kind of install this is: Origin, Steam, disc, etc.
