I've updated the seismicity map with aftershocks of today's M7.7 earthquake in Caribbean in purple. All are to West of mainshock epicenter & most clustered at about 200 km, suggesting rupture propagated to West & has length of ~200 km (expected for M7.7).

Also note that this rupture would fall inside the seismic gap here, the area of the fault without any earthquakes prior to this large event. This is similar to the earthquake in Turkey a few days ago.

are they related?

Other than that they are earthquakes with some similar characteristics (strike-slip, seismic gap), no

does the seismic gap just between the 7.7 and 6 indicate it can be filled with another big quake in the future?

The magnitude 7.7 likely already produced slip on that section. An earthquake of this size will rupture a significant part of the fault.
