At location #1 an Alien entity is leaving an energy beam. The cloudy background is due to the presence of the energy beam. Once the entity left the beam, the cloudiness was gone. This entity has been seen in the space suit types like those shown at location #2.
The entity at location #3 came out of the floater space suit. This suit is unlike previous suits. The helmet at the top separated from the body of the suit and when the entity left the suit, the suit disappeared.
Notice the features on the alien entities that are common. This is more easily seen in the images at locations 3 & 4. They have a head, a very short body, if any, and two short appendages just under the head and in addition, what appears to be two long tails.
