Could anyone please translate the following familial terms for me? Including for one's own family and also terms referring to another's…

Cousin (male)

Your basic understanding that family members of one's own and others are stated differently, although it really depends on the context.
To be more precise, even it is not your own, if you're talking about the person "on your side" to the 3rd party, you also call the family members of the person you're talking about in the same way you call your own.

Cousin (male)
Cousin (female)

Q1.: No.
Q2.: You can say 父方（ちちかた）、母方（ははかた）.
e.g. 父方の叔父： uncle on father's side.


Cousin (male) 従兄 (older than you) 従弟 (younger than you)
Cousin (female) 従姉 (older than you) 従妹 (younger than you)
All the above four are pronounced いとこ.

Grandmother –祖母 （そぼ）

Son – ????
Daughter – ????
Nephew – ????
Niece – ????

honorific
Son – 息子[むすこ]さん/御子息[ごしそく]
Daughter – 娘[むすめ]さん/お嬢[じょう]さん
Nephew – 甥御[おいご]さん
Niece – 姪御[めいご]さん

Question 1: Are there other words for a maternal/paternal aunt/uncle?

No. If you have to differentiate them, 母方[ははかた]の伯父 or something like that would be used.

Question 2: If so, are there words that express the age of the aunt/uncle relative to your mom/dad? (Ex: Is there a different word for a maternal uncle who is younger than your mother?)

father's/mother's elder brother: 伯父(おじ)
father's/mother's elder sister: 伯母(おば)
father's/mother's younger brother: 叔父(おじ)
father's/mother's younger sister: 叔母(おば)

Could anyone please translate the following familial terms for me? Including for one's own family and also terms referring to another's…
Cousin (male)
Cousin (female)

Cousin (male): 従兄/従弟/従兄弟
Cousin (female): 従姉/従妹/従姉妹
(They are all read as いとこ.)

従兄/従姉 refers to someone's elder cousin, whereas 従弟/従妹 does to a younger one. There's no difference between father's and mother's cousin. 従兄弟/従姉妹 are used pluraly.
I would use いとこの方[かた] as the honorific.
