I am starting to kitbash but my problem is that most model kits are 1:24 and i think that deluxe are 1:32. I can find a lot of diecast metal kits in 1:32 but not plastic. so my question is are deluxe 1:32?

Rarely. They aren't a fixed size. I think it's more a weightissue.

Pretty much all 'Former toys are what's called "constant scale", their scale is fixed to the pricepoint rather than the prototype vehicle (or whatever the alt-mode is based on). Hence movie Startscream and Bumblebee are both in the deluxe line, even though an F-22 is about 50 feet longer than a Camaro.
You pretty much have to compare the toy to the real thing on a case-by-case basis to get the scale.
