1) Jdm. Winken.

"Ich winke dir" is valid without "zu", but depending on where you live, unusual. "Ich habe dir gewunken" sounds less strange already.

Nevertheless, "gewunken" is wrong. The correct conjugation is "gewinkt".

As an Austrian, I've never heard anyone use "gewinkt" in a serious manner.

It is not wrong as it is the more commonly used form.

Thanks for the clarity!
