Some explanation...

1) Normally for written format, we do not use Didn't, Can't... Its only used when in speaking format. But, as a chatting purpose, we do use them still since its sort of like a conversation.

2) Didn't or Did not - means it is negative to the verb that are followed. For example: He did not sleep. This means sleep is negative = no sleep.

3) Those in green are confusing sentences. I can't understand them.

4) Much and Many - Much is used when things involved is uncountable. For example rice, water and yes, money (though i know we can "count" but it has a complicated explanation to it.) As for Many, it is used when things are countable like People, Animals, Utensils etc...
