Natural death is simply death, which is occasioned by natural causes such as terminal illness, ageing or situations like heart failure. This category of death is where the body of a human being ceases to function in its own without any external factor contributing to the same. It is commonly associated with the lifespan of an ideal human being when the body organs have performed their duties to their best capacity, and they would not function anymore.
Homicide is where a person decided to take the life of another person purposely because of inherent reasons.

Homicide may result from a person being poisoned by others or killed by police who were trailing maybe suspected gangsters, etc..
Suicide is a self-inflicted death that is purposely done by a person who wants to inflict self-harm or ultimately kill him/her through hanging, gunshot or even drug overdose.
