Your arms appear to be of normal dimensions.
On your press grip, you want to hold the bar down at the base of the palm. This will help to allow the bar to sit lower. Also, it's not absolutely necessary that the bar rests on the meat of your anterior deltoid. This is just not possible for many people. See if you can make the bar touch at the top of the sternum, just under the clavicles.
On your squat grip, you just don't seem to be making much of an effort. It looks like you got the bar on your back and then felt around for your grip. The hand placement is decided while the bar is still racked and in front of you with you looking at the bar. Get the correct hand placement. Next you duck under it and squeeze it into the correct place on the back, without changing the grip.
