I know that they all use asymmetric encryption, but I don’t understand their differences and applications. Any guidance is much appreciated!

Imagine them like physical keys.

Every one of them has the same purpose, though. It’s just a matter of how the designer decided to create the lock and the key.
Just remember that is the algorithm underneath the key that dictates the security of the key. Basically the biggest difference between a SSH key and a PGP key with the same algorithm and key length is the representation and the purpose for what it is used for.
