-I wish this night would never be over.
-I wish every one would be late.
I think the usage of 'be late, be ready, be late,...et' with the mould of would -wish? In short, the two sentences are OK for you, right?
Sentence 1 is fine, although we normally say "I wish this night would never end". It would be said during a night which, for some reason, is going very well.
Sentence 2 is very unlikely. You might wish that people would be late more often (or probably less often) but I can't think of a context for your sentence. It would be more likely to be "I hope everyone will be late" (even though that is quite an unlikely scenario too!)
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
