Question about puberty?

i am a 18 year old male and im currently standing 5'4 and i wanted to know if i may grow more in height also my penis is 4   1/2 inches erect and wanted to know if it will grow more well about me the first time i ejaculated was 15 almost 16 witch was the first time i ever thought of it anyways i don't have muscle yet like a normal men ive worked out for about 2 years and have not packed on any muscle basically also my family is full of hairy men and i have thin wispy dark black on my chin and under nose and armpit hair very little not thick at all and my nipples are almost always soft and i have allot of pubic hair wich connects from legs to belly button this is my growth pattern  
15- 4'11
summer 16- 4'11-5'1
mid 16- 5'1-5'2-5'3
summer 17-5'3-5'3 1/2-
late 17-5'4

anyways my parents are height are
father 5'8
mother-5'1
brother age 16-5'6
grandfather-5'4
grandmother-5'2
grandmother-5'2
grandfather-5'5-5'6
uncles-5'4-5'6
so will i be able to possibly make 5'5 or 5'6?

as for penis it has not really grown much last i remember at 15-16 it was maybe 3 1/2 inches erect and now at 18
4  1/2 inches erect so will my penis also grow anymore?

my testicles have hair on them already and hang down
