I think in principle a new device could support the newer power
standards and still run the data transfer as USB 2.0, but I doubt any
devices actually do that. If there were such a device it would
likely have a USB C type connector instead of the traditional square
USB B connector.

Bus powered means the entire device is limited to under 2.5W.

Rode does not provide information about the power consumption of the
NT-1A, other microphones vary anywhere from 2mA to 10mA, usually
3mA-6mA would probably be considered common, so using under 0.3W of
your 2.5W total power budget (per microphone).
The K702 spec lists the maximum input power as 200mW. That would be
well over 110dB, so quite loud.
So one microphone and headphones at deafening levels should only
account for 0.5W of the 2.5W available power. Should be no problem.

You have an amplifier between the line level outputs and your
speakers. You could always add an external headphone amp if you would
rather spend more money than twist your volume knob.

No.
Thank you very much Chris and everyone else, that puts my mind at ease.
The speakers are active (KRK RP5), so no amp in between them and the
audio interface. But since the audio interface should be able to handle
it without issue it's not a problem. Additional gear, e.g. a small
mixer, would add convenience to my setup, but it's not necessary at
this point.
Thank you very much for your helpful answers.
Best regards,
