There should be a magazine release button. And the slide will lock back automatically after you finish shooting the last round in the mag too. When you prepare to fire, you pick up the gun, load a magazine, then lock the slide (there's either a button for this, or you pull the slide back a little more and let go, you've seen this in videos, which will insert a round from the mag into the chamber. Then switch off the safety. Now the gun is hot.). It depends on the gun too. I think the mag release button should be on the other side of that Glock so you can't see it in that pic. If your friend is experienced he could run through some function drills with you.
BTW, advice from my friend that helped me the first time was also something simple and stupid, but it's true: when you're shooting, have a good / firm / steady stance and raise the sights up to your eye level. This sounds obvious, but if you see the woman in the first pic, she is somewhat nervous (this is normal), like she's thinking the gun is just going to explode in her hand. It's like the gun is in control of her, rather than her being in control of the gun. This is because guns are scary and can kill people and make a loud bang. Newbies will do things like hold the gun like that, and then try to bend down to look through the sights, rather than feeling in control of the gun and raising it up to their eye level (like the guy in the bottom pic).
