Welcome to the forums and congratulations on your new budgies!
You have a gorgeous flock there and I will take my guesses on their colours, be aware I may not be fully correct on them.
CHARLIE: I'd say is a violet sky blue full body colour greywing.
CHEEKY: I think is a sky violet yellow face type II. The cheek patches are light in colour, however the overall body colour dilution which is not present and the lack of markings make me believe this is not a greywing budgie.
DILLON: I think is a sky blue cinnamon opaline budgie.
KERMIT: single factor golden face possibly sky blue in colour, opaline full body color greywing budgie.
LULU: I think is a violet, cobalt blue full body colour greywing opaline.
PENELOPE: She's possibly a yellow face type II cobalt violet dilute budgie.
TINY: sky blue spangle opaline budgie.
EDIT: In that case, your Penelope has a violet suffusion into her feathers, she's a white based (blue series) double factor spangle and is possibly yellow face type II. You will know for sure after her first moult. If the yellow is too rich and intense in colour then she is golden face.
