Blimey. I only have one make-up bag, a small green mesh affair, and yet have managed to squeeze the following into it:
Urban Decay black eyeliner pencil
UD purple eyeliner pencil
Rimmel black eyeliner pencil
Barry M black liquid eyeliner
Coast eyeshadow (sort of greenish blue shimmer)
UD eyeshadows (one bright electric blue, one iridescent purple, one glittery black)
B Never... eyeshadow (yellow)
Barry M Dazzle Dust (one bright fuschia pink, one deep greenish-black)
ancient silver dust pot with the brand rubbed off
ditto slate grey dust pot
BWC eyeshadow due (light green/dark green)
Rimmel eyeshadow (light cream, a good base hue)
UD deep pink lip gloss/balm thing
B Never... lip tint in a pot (rose pink)
loads of scraggy cotton buds that have all been used already, no matter how hard I look
several pink emery boards
eyeliner brush
eyeshadow brush
BWC foundation
Outside the bag (they don't fit in) I have BWC translucent loose powder, B Never... blusher in Bongo

, and the brushes with which to apply these items.
I'm sure there's more; I will come back if I remember
