Just leave them be. Well, the one on the side looks like it may be pretty big. Look at the size of your sections. That's about how big the lock will be when it matures and grows out. Typically you don't want them to be bigger than 1 inch. If you do like fatter locks, join the club. I have a good detailed post about how to take care of fat locks.
If you don't want fat ones, separate a bit more of them into smaller sections.
As for washing everyday. In the beginning it wont hurt. But you really should get into the habit of washing them every other day to every 3 days. When they mature, they will hold water for a long time Up to 24 hours for fat locks. Around 5-8 for thinner ones. If you wash every day, you may be getting locks wet again that haven't fully dried. This will cause mold and mildew to grow. Eventually leading them to rot. They won't have an issue right now. But in a few more weeks you may start entering that time when you could have problems. They are doing great and moving along nicely.
