It is absolutely possible for a first aid provider to cause further injury to a casualty. For this reason, it is recommended that one only provide care that they are comfortable giving. For example, someone trained in basic first aid should never attempt to give an emergency tracheotomy in order to provide an airway. However, under normal situations, it is not uncommon for procedures such as CPR to dislocate or break ribs, even if done properly.
No. Someone with proper training is not likely to cause additional injury.

It is difficult to say whether or not it is safe for your brother to run with a leg injury. It would really depend on the severity of the injury he suffers. If he is not in severe pain, then he could likely do some light running but I would strongly advise that he asks the opinion of his doctor before taking on any further running.
The most likely threat to a casualty's life in combat is severe bleeding, followed by airway obstruction and tension pneumothorax. It is crucial to address these life-threatening injuries quickly to provide the best chance of survival.
The likely word is "injury" (physical harm).
Unless you like teeth embedded in your arm, go see the vet. Dislocations can not, and will not, correct themselves. The dog needs to be anesthetised before anyone can safely reset the joint. Doing it yourself will likely result in injury to you and further injury to the dog.
An insect bite would be considered a wound, which is another term for a minor injury. However, if the bite caused an infection or triggered an allergic reaction, that would more than likely upgrade the situation to an injury. And if the bite happened to be the vector for an insect-borne disease (such as West Nile virus or malaria) you might even upgrade it further by labeling it the entry point of a chronic condition.
