Hey Jordan,

I gave it a try and look for the locations, specially the 3rd one that does indeed look like it could be in Chile.

For the 2nd picture I found an island in the French Polynesia that has very similar colors and characteristics, might be its around that area, 8°56'10.8"S 139°34'41.2"W (-8.936304553977038, -139.57811272908305)

For the 3rd picture I found many locations that look like your picture but really couldn't find one. The first one is around Mexico, though it probably isn't 27°32'39.0"N 114°45'00.5"W (27.544166, -114.750130). And the second one are islands close to Morocco 28°01'54.4"N 17°16'22.9"W (28.03198233652239, -17.27306308433365) though the angle is not the same... As a bonus for the 3rd picture, I did find in the Andes mountain something that looks like your picture: 33°38'11.7"S 70°07'01.4"W (-33.636446, -70.116968). So maybe you should also look around mountains.

At least from what I've seen in Chile the coast is usually very rocky and the water is usually lot of waves, and in the picture it looks really smooth. (Though I don't know how zoomed out the picture is)
