What do these cholesterol numbers mean?!

What do these cholesterol numbers mean?

My husband is 35- high blood pressure and high cholesterol run in his family. He is currently taking BP medication.

So the most recent blood work shows the following:

Total Cholesterol is 203 (needs to be under 200)
HDL is 65 (should be greater than 39)
LDL is 77 (should be less than 130)
Triglycerides is 305 (should be under 150)

***the stuff in parenthesis is what we were told***

That being said. His tri level has dropped from 489 to 305 with the minor diet changes he has made in the last few months.

What do all these number mean? Would most Dr's suggest putting him on medication if he is improving his numbers through diet? (he doesn't want to start taking meds just yet but he will if he has to)
