Raising volume of one mic in an audio track to meet others' mics volumes
For it to sound good, you would certainly have to raise and lower the volume by hand using keyframes. If you want a quick and dirty solution, you can use a limiter or compressor. A limiter sets a ceiling of volume that cannot be surpassed. This way, you can turn up the volume significantly, which would make your voice touch this ceiling while others would be crashing through that ceiling. The limiter than lowers the volume of the parts that would crash through the ceiling, effectively putting loud and quiet parts closer together in volume.
However, you will also hear an extreme limiter / compression like this. Quiet sounds when nobody talks will be awkwardly loud, breaths sound like from an asmr video and you will most likely have a problem with background noise, which will be more audible aswell.
To avoid this problem in the first place, I would recommend you use microphones for each person that's speaking, so you can adjust the volume easily in post-production.
