Generally ok I think.

4a. They no longer have to work for a long time.
4b. They don't have to work for a long time any longer. [Is this awkward?]
No it's not awkward.

5a. The city provides us with safe and clean water.
5b. The city supplies us with safe and clean water.
[Do 5a and 5b have the same meaning?]
Yes, same.

6a. Mike has been working on the difficult math problem for a week.
6b. Mike has worked on the difficult math problem for a week.
[Can 6a and 6b have the same meaning?]
Basically same meaning imo. 6b implies that he may be no longer working on it.
I think it would be more natural to say "a difficult math problem" than "the difficult math problem." The latter means a specific problem. If it was such a specific problem, probably it would have a name like "Mike has been working the Pythagorean Potato Hypothesis for a week."
