Several mods won't show up in the mods thing on the title

[striker1919]

So I'm not a huge nerd when it comes to mods, but what I do know comes from friends. Anyways, there are a few mods that I have trouble with. The Hidden Doors Mod, which I read on the forum page requires ModLoader, but from research I found FML is a substitute of that. Either way, when I put it into the mods folder Forge doesn't pick it up. Also, I have tried the DamageIndicators Mod, Car Mod, Pet Bat Mod, InstantMassiveStructures Mod, and the DivineRPG mod. None work. Also, when I use Not Enough Items, I put CodeChickenCore and NEI jars in the coremods folder, as the website says, and a folder of it in the mods folder. It works in MultiPlayer, but crashes my SinglePlayer worlds* when I try to go in them. I am absolutely positive that I have the most recent update for Forge, so I don't what the problem is. Help?

 

Thanks, striker1919
