Tropicals & Tender Perennials: Will these cuttings survive?, 1 by Quyen

I'm brand new to brugs. My aunt got too many cuttings from a friend so she gave me a few. I know next to nothing about brugs. I stuck the cuttings in a vase of water. See pic. There's suppose to be two yellows, one white, and one pink.

Will they live?
Should I use sand instead of just water?
Should I change the water everyday?
How long will it take for roots to form?
Do they like shades or sun?

Anything else I need to know? Thanks for your help.
