Do different types of hashes take varying amounts of time to crack?

The simple answer is yes. The hash has a lot to do with it. With simple types of hashes you can get billions of tries per second (thats why they're called fast hashes e.g. MD5, NTLM), but with more secure ones you fall back into millions, thousands or even hundreds (e.g. WPA, bcrypt).

You can perform a benchmark with your card (option -b) and see how fast it'll be at which type of hash.
