Help needed with new concentrates

[vaporiser]

I got a few new concentrates today from Chefs Flavours thanks to some recommendations on here. Thank you again
I chose Absinthe, Blue Raspberry, Brazilian Orange, Cookies N Cream, Reeces & Skittles. And they very kindly sent me another concentrate as a gift which was California Dreaming - vanilla milkshake type flavour.
So I've got the concentrates I wanted... now I just need to know what I got to do next lol. I want one or two flavours I can use straight away without needing to steep them.. which one are suitable for this? Which concentrates should I mix? And of course once I've got that figured out I'd like to mix some concentrates together to steep for as long as necessary.

Other concentrates I own are...

Apricot, Cappucino, Caramel - from The Perfumer's Apprentice
Banana, Apple (Green Caramel) and Cream (Milky Undertone) - from One On One
Yellow Peach - from Capella
Rocky Road, Snickers, Spearmint - from Flavor West

Any advice on what I can do with these? I want to make 1 or 2 e-liquids for instant vaping and then some for steeping.
