An indirect object doesn't ask, an indirect object tellswho or what gets the direct object. Example:
Let's buy some flowers. What will we buy? Flowers, the direct object of the verb buy.
Let's buy mom some flowers. What will we buy? Flowers, the direct object. And, who gets the direct object (flowers)? Mom gets the flowers; mom is the indirect object.
An indirect object can follow the verb, coming before the direct object; or the indirect object can be the object of a preposition: Let's buy some flowers for mom.

Difficult is an adjective, so no, it cannot be an indirect object. Indirect objects are nouns or pronouns that receive the direct object.

In English, both are in the objective case and both are complements of verbs as part of a complete predicate. (In many other languages, such as Latin and German, there is a separate "dative" case for indirect objects.)
Indirect objects answer the questions "to whom?", "for whom?", "to what?", or "for what?" in a sentence.
Indirect objects are best seen as having the word 'to' omitted. In "He gave him an apple" the direct object is 'an apple' and the indirect object is 'him'. It really means 'to him'. So indirect objects are nouns or pronouns.
Only transitive verbs have direct or indirect objects

It's unusual for a number to be used as an indirect object, but it can be done. For example, "Give the three of them the answer to question #7." In that sentence, "three" is the indirect object.
Indirect questions do not require question marks because they are structured as statements rather than direct inquiries. For example, in the sentence "I wonder where she went," the phrase "where she went" is an indirect question and is punctuated with a period. In contrast, direct questions, like "Where did she go?" do use question marks.
Yes. Marcy sold Joe and his little brother three pizzas for her fundraiser. Marcy is the subject. Pizza is the direct object, because Marcy is selling the pizza's "directly." Who did she sell them to? Joe and his little brother. Thus, Joe and brother are the indirect objects.
