I am extremely jealous of my former best friend who now is hanging out with another one of my former best friend and none of them are calling me their best friend and it really hurts.
Jealousy isn't rare - many people feel it now and then. Although I don't know EXACTLY what it feels like to to be in a situation like this, I can empathise with you and understand the feeling of not being wanted as much by someone who meant so much to you. My advice is if you want to rekindle your friendships, start again from the beginning. Talk to them and hangout more. If you want to move on, my advice would be to just have some time to yourself and think of something that will allow you to move on to the next stage of your emotional growth. Also, talking to the two of them and being completely honest about your feelings never hurts!
