In general, you have done reasonable work, because you seem to catch the sense of the text. Here are some hints to help you in future exercises and to correct the present text.

One good way to do these problems is to translating mentally and reading it aloud to check if it makes sense, sentence by sentence if preferred.

Another good practice is to group words that frequently go together and see if they make sense in the text.

For example,
"devraient" goes with a subject which is third person plural, and should necessarily be followed by an infinitive verb which may be on the list (être is the only one) or in the text.

When you fill in the words, make sure the function of the word works in the sentence. For example, for #6,
Il se doux et...
does not work because doux is an adjective, but you're looking for a verb (third person singular), so you need to go through the list to look for one that fits.

Answers (1), (5), and (7) are correct.

The other numbers can be readily corrected using hints and methods I mentioned earlier.

To fill in the blanks in the given phrase, you need to choose the correct word from the word bank that best fits each blank. Let's go through each blank:

1. The phrase "La semaine prochaine, il est certain qu’il ne ___(1)___ pas du tout." implies that it will not rain at all next week. Therefore, the correct word to fill in the blank is "pleuvra".

2. "Il ___(2)___ certainement plus ___(3)___.": Here, the context suggests that something will certainly become or be more something else. The word that fits in this sentence is "devraient".

3. "Il ___(2)___ certainement plus ___(3)___.": According to the previous analysis, we need to find an appropriate adjective that describes that something will certainly become or be more of it. Looking at the word bank, "radoucira" is the word that fits this description.

4. "Les températures ne ___(4)___ pas ___(5)___ très élevées.": The phrase mentions that the temperatures will not be very high. Therefore, the correct word to fill in the blank is "fera".

5. "Les températures ne ___(4)___ pas ___(5)___ très élevées.": As discussed in the previous analysis, the phrase refers to the temperatures not being high. The word that fits this description is "être".

6. "Il se ___(6)___ et nous ___(7)___ au lac faire un pique-nique.": This sentence implies that "it" becomes something else, and then "we" do something. Looking at the word bank, "doux" is the word that fits the first blank, while "irons" is the word that fits the second blank.

By filling in the blanks with the correct words, the completed phrase would be: "La semaine prochaine, il est certain qu’il ne pleuvra pas du tout. Il devraient certainement plus radoucira. Les températures ne fera pas être très élevées. Il se doux et nous irons au lac faire un pique-nique."
