Red filter included with contrast filters...

I thought B&W VC paper was sensitive to red light - and that's why
there are the amber filters for safe lights. Must be just a certain
spectrum of red?

It can look red but still emit in the sensitive part of the spectrum for your paper.
Like presumed inactinic lights, it's a good habit to check it from time to time.

along with the filters (in the same box but not cased with the other
filters) there is also a red filter (very RED red) same construction
but has it's own case - what's this for?

Focusing on the paper.

VC paper is sensitive to blue and green light, insensitive to red.
Panchromatic papers like Panalure and all color paper are sensitive to red
green and blue light but there is a gap in sensitivity where the dark amber
"safelight" resides. Probably more correct to say less "un"-safe rather
than truly safe.

Mike (Darkroom Mike) already explained the sensitivity issue. However, like
I said my the last sentence in the above post, you should always test, just
like a safelight...
