I am wondering if it's good enough or if I have to ensure that all the female threads make contact with a male thread.
Welcome to DIY Chatroom
If you have doped the male threads (personally I dope & tape) you simply tighten until it's good and tight - about 7 threads should be buried in the female fitting. Sometimes a little less
The threads are a tapered pattern so eventually it will be tight. Call it good when that happens. Having left over threads exposed is normal
