I think your friend has sent you some nice products. However the night before an event is not the time to start experimenting (that comes later). So I suggest: stick to the basics for tomorrow. Youtube is a gold mine of good tutorials but for tomorrow here is a simple plan.

1. start with a clean, moisturized face
2. apply a pea sized amount of the BB cream with your fingers - start out with less than you think you'll need to cover your face and add more as you see fit
3. eyeshadow: pick one and use one of the brushes with a short paddle shaped head to apply it over your entire eyelid - I suggest the light pink on the top left.
4. use the mascara and apply one or two coats
5. use the angled brush to apply blush on the apples of your cheeks (smile to see where the apples are) - start with a thin layer and apply more as you see fit but be judicious

6. apply a lipstick (can't remember if I saw one in your haul) but I suggest pick a colour close to your own lip colour (darker shades are great but need to be applied more carefully)

7. For tomorrow I suggest skip the eyeliner, bronzer, contour - all are great but all have a learning curve (in my experience) so leave those till you have had time to practice a bit
