To me, It depends on the shade of purple
Yes.
Purple is not a single color. Maybe a spectrum analysis could answer this for a given instance of purple, but that’s not my area of knowledge.
Surgically, purple is not a wavelength, unlike red(s) at ~700nm and blue(s) at ~400nm.
Purple is what human eyes see when the blue and red cones are both stimulated by their respective colours of light.
Right, indigo is a color (~425nm), violet is a color (~400nm), purple is typically a blend of colors.

Fun fact: blends of colours are also colours.
Nu uh!
Okay, poor choice of words by me. Wavelength color vs what the eyes see.
Yes
It’s anti-green
Depends on what shade of purple
Purple is a group of colours in between of blue and red, but unlike Indigo is leaning toward red (hot).
Lukewarm purple?
Purple is a kind of red to me.
All colors have cold and warm variants and can work in surprising ways when used in color compositions.
First one, then the other
It depends on the definition of purple.
