I think the main one was mustard gas, a skin irritant which causes blindness. Phosgene was also used. It wasn't only used by the Germans.
There were many types of poison gas used in WW1 such as Chlorine, Diphosgene, Tearing Agent, or Blistering Agent. Blistering was one that smelled like mustard while being manufactured, which is why it is known as "mustard gas." It caused blisters that one could die from.
