An user said this ((5 moods × 2 tenses) + (1 defective mood)) × (4 aspects × 2 voices) But what I don't understand is about the moods that he/she mentioned.
Indicative, Interrogative ,Subjunctive and what else?

The user is using "mood" to refer to modal verbs indicating the speaker's attitude to the verb. They list them right in the answer.
Really we have 4 modal verbs which occur in present/past tense pairs: will/would, shall/should, can/could, may/might, and then must which can only be present-tense.
For more details, see the answer you linked in the question, in particular the section titled "Now you've made me upset" (this is a play on words).
Oxford's answer in Grammar A-Z (I have changed the order):
Mood
1 indicative mood, expressing facts
2 subjunctive mood, expressing wishes or possibility
3 conditional mood, expressing a condition
4 imperative mood, expressing a command
5 interrogative mood, expressing a question

You don't speak of defective mood, only of defective verbs, verbs that have not all possible forms.
Mood and aspect are different things. Mood describes how a statement is meant, as something real or not real, as a wish, a command or a question.
Aspect describes how an action is seen, in English mainly in progress or not in progress. Other languages can have forms that stress the beginning or the end of an action or a habitual action.
Those who insist that English grammar has something to do with Latin grammar will tell you that I will go is a tense while I would go is a mood. This is plainly nonsense: they are syntactically indistinguishable, and classifying them as different on the basis of what they would be if you translated them into a different language is simply mad.
