Active acquired immunity occurs when you get an infection by a pathogen (bacteria, virus) and your body responds and removes the pathogen and also your body makes "memory" cells. These cell remember this pathogen and when it enters your body again you remove it immediately. You are now immune to it. You usually don't notice this.

Natural Passive Immunity
You need to be more specific. Do you mean the Naturally acquired active immunity process or the Artificially acquired active immunity process? Both are of the Adaptive Immunity process. There are also passive processes for each.
Active immunity is long term protection that generally lasts 20-30 years and passive immunity is immediate protection. there are two forms, naturally acquired and artificially acquired. in active immunity the naturally acquired immunity is when you suffer from the disease then recover again. the artificially acquired way is by getting a vaccination. in passive immunity, the naturally acquired way is to receive antibodies from mother in pregnancy and breastfeeding, the artificial way is to have antibodies injected in a serum for immediate response for example when you have been bitten by a poisonous animal. note they are not vaccinated.
A person acquires active immunity when their own immune system produces antibodies in response to the presence of a pathogen. Active immunity can result from either getting the disease or being vaccinated.
Artificially acquired active immunity.

Tetanus shots protect against diphtheria, tetanus, and pertussis.
The response to infections is active or cellular immunity. Acquired immunity
Naturally acquired active immunity is the type of resistance that is acquired from developing a disease. Naturally acquired active immunity leaves the person immune from developing the disease again in the future.

There is innate immunity (that you are born with) and acquired immunity. Acquired immunity you get when you are vaccinated or you get the disease and fight it off. The best example is that of what we call common colds. There are about 100 different viruses that cause them. This is one reason that babies and young children seem to be always be coming down with one or getting over one.
