What is the difference between the two HP band types? And the two LP band types?
-- the first of each has a Q control and Slopes from 12 to 120 dB/octave,
-- the second of each does not have a Q control and Slopes from 6 to 60 dB/octave.
Why have both?
Is one 'resonant'?
What is the implied Q value for the second of each?
Q: MEqualizer: HP and LP band types

The one with Q is resonant, the one without is not.
Also, you'll notice the slope amounts aren't quite the same, the lowest the resonant one can go is 12dB the non resonant goes to 6dB. The highest the resonant one can go is 120dB, the non resonant goes to 60dB.

Ah ha, so my guess was correct.
FR: Perhaps the resonant ones can be so labelled (as in MDynamicEq, which, incidentally, does not have the "non-resonant" types).

Here's the follow-up question:
I created the same HP and LP filters in MEqualizer and MDynamicEq and sent the same sine-wave to them both. The resulting EQ curves were different and MEqualizer reduced the level.

Shouldn't they be the same? (I'm pretty sure that I have not missed anything.)

The order there is just "because we can" 
. Other than that both filters work rather differently, but their effect would be similar with appropriate orders and specific Q (1/sqrt(2)). The 6dB/oct HP/LP is probably useful only with order 1, but you never know what people come up with 
.
And there may be differences between MEqualizer and MDynamicEq (which has newer filters). In your case I'd expect difference in settings though.
