Video 1:
0:20 : A light object travelling in a straight line. Could be a block of ice or something else reflective.
Ooft. That is one fast-moving block of ice, laddie. Or something else reflective? Judging by your other comments, there certainly are a lot of very bright shiny things moving around in space at high speeds

You seem to imply a lot that something's flying in a straight line precludes its being piloted by intelligent beings. Of course, planes also fly in straight lines. But, of course, changing direction is more indicative of something that's being piloted by intelligence, you're right in that.
As for the thing at 2:05, it moves very fast. Given the moon's comparitively weak gravitational force, I doubt it could be chalked up to gravity.
Video 2:
0:18 : It doesn't decelerate, the video is played fast and then slowed down. The change in direction is immediate and in a straight line, this could easily be due to an impact with an object that is dark and not reflecting light. Space debris collision + forgery of the video footage.
0:40 : Changes direction smoothly so doesn't look like a collision.
2:10 : Reflective object moving according to the laws of physics, nothing unusual there.
3:10 : Occurrences during an electrical storm, these could easily be some kind of electro magnetic phenomena.
5:30 : Didn't listen. Human accounts are notoriously inaccurate, I want to see video footage.
8:40 : Again reflective objects moving with uniformed motion.
0:18 It's possible, although an alternative explanation is likewise.
0:40 What could it possibly be?
2:10 Could be something mundane, could not be
2:30 Also has some interesting things, something very fast-moving darting off in the direction of the earth, then something looking like it pops into existence out of nothing.
3:10 Or, failing that, some other unexplained phenomenon. But I think it's interesting that some of them come from space, and do not seem to originate from the actual location of the storm itself.
5:30 The guy was an astronaut, and talks about how the existence of aliens and the like is acknowledged within circles of government scientists and intelligence people. Maybe it's not true, but it's worth considering.
8:40 So what? How does that explain what they are? One stationary and two moving at different speeds. Doesn't seem like random peices of ice from the space shuttle.
Video 3
0:15 : Uniformed motion
2:18 : Much better, no explanation
2:55 : Reflective + uniformed motion
3:00 : As above
5:20 : No idea, but I distrust still photographs because they are not revealing enough.
0:15 Like I say, that doesn't explain much. Could be something uninteresting. Must be travelling very quickly though, and in a perfect straight line, seemingly undisturbed by the moon's gravity.
2:18 Yep, it's a good 'n'.
You might also find 2:42 Interesting. Bright object, constant speed, changing direction. Or, if you can be bothered, just watch the the vids in their entirety. There could well be other stuff that I missed.
2:55 I dunno. It flashes, yet doesn't change shape as would be expected from a rotating object. That and one of them is followed by a similar-looking object.
5:20 I think I meant to type 6:30 for that. A bright object, changes speed gradually and then remains static.
The thing at 9:00 is interesting. Like some of the other ones with objects appearing to pop into existence, some things come from space, etc. Very strange, whatever it is.
If you have more of the ones I could not explain then those would be interesting. What I don't want to see is
1: A light moving in a straight line : This is just light coloured space debris reflecting sun-light, like a chunk of ice etc.
2: A light changing direction from straight line A to straight line B: This is just #1 after a collision.
3: A flashing light travelling in a straight line: This is just #1 where the object is flattened and rotating.
4: Things which occur during electrical storms.
I'll see if I can find more of the good ones

1: Not necessarily. But I understand that there's no reason to believe that they're necessarily anything different either, let alone alien space ships.
2: Same as above
3: Not necessarily. Such objects must have a particular shape. But a number of these flashing objects do not change shape, which may indicate that their flashing is not the result of mere rotation and the reflection of sunlight.
4: Those same objects can be seen in the last video at 8:50 onwards, not during an electrical storm. There's another similar example in 2:30 of the second vid
