I understand that there are two types of ways proteins are used in the plasma membrane; channel and carrier proteins. What is the difference between the two? How do they both work?
Thank you in advance!

Carrier need energy (Active transport)
Channel require no energy (Ions etc travel down concentration gradient).

I'm not sure about the terminology you use for whatever level you're studying at, but aren't channel proteins a subtype of carrier proteins?
Proteins in the cell membrane (let alone any other plasma membrane) are far more diverse than just those two types though, so if that is your understanding I assume you are studying at a level where the answer is more exam board terminology than reality (don't take that the wrong way).

I know that, but are the types of molecules they allow through differ?

carriers typically carry ions (charged molecules) through a membrane
