Well if it's an arc then I number them.
Like Chen Banquet (1), Chen Banquet (2),... So on.
For individual chapters sometimes I base the name on any important dialogue that is the crux of that chap.
Or I write something that defines the overall summary. Sometimes I do find it difficult to give a name or I feel that there is nothing major happening in chp that I will get a name for it. That time I don't think much and just give any random one relating to it not caring if it's interesting or not.
Just like how we cannot end all chps in a cliffhanger similarly we cannot give interesting names for all chps.
