Her A times seems about right, there is one a bit long but there is not much to do about it right now; if you'll shorten it you have a long A before BT time. The waking up at night and chatting *could* be a bit UT, but if it's not a problem yet and she is resettling in short time then I wouldn't change anything in the routine yet. If it does become a problem then you can try and increase her A time by 10min, though I'll be cautious doing that as she is already high on her A times.
It's still normal for her to have a NF at 4. In fact many babies still have 2NF at this age so I wouldn't worry about it now.
