An ordinary blister caused by burning or rubbing contains an almost colourless liquid. It's mostly bodily fluid, IE lymph and plasma, which is the fluid blood, the straw coloured liquid that contains the blood cells. Lymph is formed from plasma and forms another circulatory system, which helps to fight infection but does not oxygenate the tissues. These two together form the interstitial fluid, which bathes the cells of the body.
The purpose of the blister is to protect the injured area. It should not normally be broken as it is sealed and this helps to prevent infection. The liquid is there partly due to the injury- the fluid is leaking out of the underlying tissue, and partly it acts as a cushion and protects the site of injury.
The liquid is mostly water, but contains various salts and traces of various organic compounds.

A blister is a bubble of fluid under the skin. The clear, watery liquid inside a blister is called serum. It leaks in from neighboring tissues as a reaction to injured skin. If the blister remains unopened, serum can provide natural protection for the skin beneath it. Small blisters are called vesicles. Those larger than half an inch are called bullae. A blood blister is filled with blood, rather than serum.

A blister or bulla is a defense mechanism of the human body. It consists of a pool of lymph and other bodily fluids beneath the upper layers of the skin. It may be formed in response to burns or friction, and helps to repair damage to the skin. If a blister is punctured, it forms an open wound and should be bandaged to prevent bacteria and dust from entering the wound which could result in inflammation.
If a blister is associated with sub-dermal bleeding, it may partially fill with blood, forming an unpleasant blood blister.
Blistering is a distinguishing characteristic of second degree burns.
Certain autoimmune diseases feature extensive blistering. These include pemphigus and pemphigoid. Blistering also occurs as part of foodborne illness with Vibrio vulnificus (seafood).
The class of chemical weapons known as vesicants acts by causing blisters (often within the respiratory tract). Mustard gas and lewisite are examples of such agents.

Lymphatic fluid that contains lots of lymphocytes that are there to stop the blister getting infected. So don't burst your blisters!

It is called "pus". It is a yellowish fluid consisting of bacteria, leukocytes, serum, and dead cells from inflamed tissue.

What an interesting question. I, up until now, had never given that any thought. I can't answer your question, I'm sorry. It's a good one though.
