Tell Jake not to be afraid. Orbs are souls, that's their natural form. They can take other forms, such as ghosts, but that is what they normally look like. Most likely they are spirits who are around him to protect and guide him. They are probably grandparents or relatives that have passed on. It is common for our relatives to come check up on us. Tell him he that other people can see them if they practice and learn for a long time, and he is lucky to be able to see him with such ease. In fact, most people can capture them in photographs and videos but not with their eyes. If you search the internet you can probably find photographs and show him. Good luck and let me know if you need more help.
