These are my guesses:
Zip - Someone from a boy band. There are lots of boy band related clues, so maybe Howard Donald as he seems very good at breakdancing. The jelly and icecream clue in the VT may be to do with "Do what you like", TT's first hit.
Scarecrow - Faye Tozer? Louisa Lytton? The latter was in The Bill and Eastenders but the start of the dance really reminded me of Faye's charleston dance in Strictly and she also did a quickstep to "You're the one that I want" and there was a Grease reference in the VT.
Squirrel - Not sure. Possibly Janette from Strictly or even Debbie McGee.
Carwash - Someone in the sporting world. Having done a bit of googling with the clues, Matt Baker or Louis Smith.
