Yes.
No. "I have known him for 5 years." Would be more correct.
No, it is not grammatically correct to use both an exclamation mark and a question mark at the end of the same sentence. Choose one or the other based on the intended tone of the sentence.
"This is absolutely magnificent you love the family tree" is meaningless. It might perhaps be "It is magnificent that you love the family tree" which is grammatically correct. But is a very peculiar thing to call love of a family tree "magnificent" because a family tree is a list of parentage, never known ever to be "loved".
If you use the "had" it implies that you no longer know this person. I had known means I don't know now. I have known means that you may or may not know her now.

A kernel sentence, also known as a basic sentence or a core sentence, is the simplest form of a sentence that contains a subject and a predicate. It expresses a complete thought and can stand alone as a grammatically correct sentence. Kernel sentences serve as the foundation for constructing more complex sentences.
Psoriasis is a skin condition that causes the skin to be red and flaky also known as scales. Depending on the severity of the psoriasis, creams and lotions have been the typical treatment for psoriasis patients.
I believe my offices and I are well known.
Both are correct, with different meaning. If I wasintroduces a real condition in the past, and if I wereintroduces an unreal condition in the present. For example: If I was hungry I ate and If I were hungry I would eat
NoThe sentence "You should of known better." derives from "You should've known better."; "should of" sounds about like "should've". Of course "should've" is a contraction for "should have" so the correct sentence is either "You should have known better." or (if speaking informally and using contractions) "You should've known better." Writing the sentence as "You should of known better." instead of "You should'veknown better." is INCORRECT.

Psoriasis is hereditary. Therefore, there is a possibility that the child would have it if his/her parents have a history of it. Since psoriasis is rare, we cannot determine if a skin disorder is a psoriasis type or not. Precisely, some skin disorders are psoriasis-like diseases but are known as dermatoses after the biopsy. Back to psoriasis, biopsy and lifestyle information is needed to determine the type of disease.
