Right away I like Jude Samuel better than Jude Alec; then you have the 1-3-2 instead of 1-2-2 for syllables. It has a nicer flow to it!
Beatrice in my mind is a better fit with Jude. I'm around age 20 and I have 5 close friends named Hannah! It's extremely popular with my generation!
I think Jude and Beatrice have a similar feel, they are vintage and quirky but also fairly familiar without being popular.
While I think that a 1 syllable middle would go nicely with Beatrice, that is just me being picky. Beatrice Renee sounds nice!
