For scale the leaf size is 4 inch long
Second try for the picture (sorry)
Your plant looks to me like a form of Hoya pottsii, this one is also often called Hoya nicholsoniae.
Are those aphids on the other bloom that is forming? I get those on my hoyas sometimes. I just take them down, take them outside and spray them off with water. A big preying mantis has moved onto one of the hoyas on the porch and he ate the ones on that hoya. I just spritz the leaves with water...in between watering it...to give him a drink.
