I take hydralozine, clonidine, amlodipine, coreg (carvedilol) and losartan for hbp and thyroxine. could any of these medications cause erectile dysfunction?

ED: Yes:- but having elevated BP by itselof can be an issue in ED. I suggest reviewing this with your physician.

Yes: Core and Clonidine and less likely but possible Hydralazine. Amlodipine and Losartan are usually not the cause of ED.

Yes: All of the drugs mentioned above with the exception of thyroxine have erectile dysfunction as a side effect.

Beta blocker and ED: Erectile dysfunction has been reported with the use of coreg (carvedilol) and other beta blockers

BP meds can do this: Impotence are listed potential side effects of hydralazine, amlodipine and losartan. Potentially, any of the antihypertensive medicines can do this. It is uncommon to require 5 different medicines to control hypertension. Ask your doctor to reassess your treatment
