Yes 6 inches is a good size for a penis that is only 14 yrs old. Heck alot of full grown men do not even have 6 inches, and yours still has alot of growing to do for at least 4 to 5 years longer.
It is adequate.
It is within range (5 to 7 inches).
No, it's fairly normal.

I'm 15 and i have a 8 and 1/2 inch penis and the average penis for a 15 year old boy is 6.2 inches when erect and 4.1 inches around
Not to sound rude but i highly doubt that u have an 18" penis
Yes, average adult male size is 4.5 in

That is perfectly fine.
We don't know. Some men have an 8, 9, 10 inch penis. Very seldom bigger. We can't say how big your's will be.

If it is large enough to successfully urinate, stop worrying about. It's fine.
