Ok....
On the first video, your last rep looked the deepest. They were not below parallel, but it is a start. Everything else looked good from that angle and what I saw, although I agree with asooney - push your knees way out to the side to allow your pelvis and torso to clean in order to go lower.
On the second video - keep your elbows up. Your upper arms should always be parallel to the floor.
The final video with no weight looked good. As your hip mobility improves, so will your front squat and you ability to achieve a greater depth. Right now, I would focus on getting to the depth you were in the final squat in the first video, and the depth of the last video. Also, focus heavily on working to improve mobility via active mobility drills both as a warm up and also as an active recovery spaced about 1 or 2 days following squat day.
