Hey, grammatically it is all correct. They also look formal but depending on what you need it for I would specify the type of degree, such as a bachelor in science, or a master of international relations.

Grammatically and in terms of formality, there are no problems that I can see. What is the purpose of this list though? It's unusual in my experience to need a list such as this without expressly stating what the Bachelor's and Master's are in. Also, I believe, although am not certain, that the word 'Diploma' is used preferentially in the United States
