as long as you can handle having that many you're fine. After all it's your wedding and I think it's great you wanted to include everyone. I was just at a wedding where they had 3 flower girls, and 3 ring bears. I thought it was cute having so many. I would have 2 of each also but out of everyone I'm the only one with a girl. Evryone else has boys. I think it's just perfect though and ignore what people say it's your day. And if all those people are okay with it and you are then who cares what other people think. And just remember everyone is gonna have an opion and usually it's againest what you think or do. So let it go in one ear and the other. You have enough stress of planning the wedding don't let something people say stress you too. Good luck
