Sure! Here"s the detailed and thorough answer to your task, with explanations for each answer:

Wendy: I hope you 1) will be able to come to the surprise party we are organizing for Kate this weekend.

In this sentence, we use "will" because Wendy is expressing her hope or expectation for the future. It is also common to use "will" when making polite requests or invitations.

Emma: Of course I 2) will, Wendy.

Emma responds by saying that she will be able to come. Since she is giving a positive response to a request, she uses "will".

But I"m afraid my sister Harriet 3) won"t be able to come.

Emma explains that her sister Harriet won"t be able to come. Here, we use "won"t" as a contraction of "will not" to express a negative statement about the future.

Wendy: Oh, that"s a shame! Kate 4) will be disappointed about that; she really likes your sister.

Wendy predicts that Kate will be disappointed because she likes Emma"s sister. In this case, we use "will" to talk about a future event or situation that we believe is certain or likely.

Emma: How many people do you think 5) will be there?

Emma asks for Wendy"s prediction about the number of people who will attend the party. We use "will" here to talk about a future event or situation that we believe is certain or likely.

Wendy: Well, I"ve invited everyone in the class and so far 15 people have promised they 6) will come.

Wendy explains that she has invited everyone in the class and 15 people have already confirmed their attendance. Once again, we use "will" because these people have made promises to come in the future.

Who else 7) should I invite?

Wendy asks for Emma"s opinion on who else should be invited to the party. Since this is a suggestion or a question asked for advice, we use "should".

Emma: How about the girls in the netball team?

Emma suggests inviting the girls in the netball team. This is a suggestion, so we use "should" to express the idea of what is recommended or appropriate.

Wendy: That"s a great idea. They 8) will

Wendy agrees with Emma"s suggestion and completes her sentence with "will". Here, it is implied that Wendy is saying, "They will be invited."
