In our area, the cheapest protein that isn't in powder form and from an animal source is cottage cheese. Eggs are cheaper until you factor in the protein in a serving of either versus the calories and cost per ounce. Dried pinto beans are perhaps the cheapest source of protein but some athletes prefer animal protein for building muscle mass. If you can handle lactose or beans either option would be a good protein source. However, because they are not pre-digested or overly processed your body will take longer to digest them and so may cause some discomfort if exercising immediately after a meal. Arguably, if you have access to hunting in your area, wild game would be hands down the cheapest source of protein. Before hunting be sure to check with your country's laws and updated information on viruses infecting local animals that may affect your health.
I would start of with the fact that it can (most likely) only be 2 of your 3 variables at a time. If it's cheap and healthy, it might not be natural (protein powder for example). If it's healthy and natural, it's most likely not going to be the cheapest and if its both cheap and natural, it might not be the healthiest.
That being said, I'd say the most natural and healthy is going to be plant based protein. Different types of beans, nuts, seeds and vegetables for example. This might cost you a bit more though.
The most natural and cheap is probably going to be animal based protein like eggs, cheese and meat. This might not be as healthy as plant based protein if you consume loads.
