it doesnt look like the fence actually cross the road at this point

all these buildings should be retagged as rooms or building parts and not as buildings, then one building area for entire building should be added on top of the structures that are buildings.

is this poi node/2383254155 really a post office or just a government office?

new buildings have been built here and can be added

parcel needs updates to building outlines as new construction has occurred here and there are new buildings now

pois here look misplaced, they are not in this housing complex from what I can determine, should be moved to their correct locations: node/358851662 and node/358851652

airport poi could be merged with the heliport poi here... probably best tagged as heliport anyway

these are not lighthouses, they are seamark beacons and should be retagged per: osm.wiki/Seamarks/Beacons

from aerials this airstrip looks abandoned suggest tagged as such if that is the case. landing areas via usgs topo do not look in use anymore...
