Triglycerides is 210 and my ldl is 165 is it risky?

Depends: It depends on your current risk factors: smoking, high blood pressure, diabetes, past heart attacks, peripheral arterial disease, family history of premature coronary artery disease, age, HDL level...See your doctor who knows your history to figure out your goal.

Yes: If ur total cholesterol is above 200, subtract from hdl, if that number is above 100-130, i would a statin or fish pil.

Yes: Triglycerides should be half of cholesterol, LDL creates damage to vessel wall - should be in 100's. Use carnitine 2gm per day to normalize both.

Risk depends on much: "normal" triglycerides (tg's) are <150 mg/dl. When elevated they can be associated with changes in "lipoproteins" that may cause heart disease. Not everyone with elevated tg's has this problem. "ideal" LDL is <100. There is a condition of elevated tg's and LDL called familial combined hypercholesterolemia, associated with increased risk of heart disease. See your doctor.
