Some nouns don't like to take a plural form. A couple of examles are
fish and
sheep. I have a feeling there may be a "rule" regarding nouns made from adjectives like aggression, happyness, that they can't take plural form ether. I don't have a dictionary nearby, but please check.

4. That's it, no more houseguests.
guests are countable
5. There is so much light over there.

10. When you come to situations like this....

This depends on whether you are thinking about dialogue as a countable or uncountable thing. It could be either.
That was all just off the top of my head. Hope it helps.
I think if you study up on countable/uncountable you will understand better.
