You raise something when you move it so it is higher than it was before.
The people in the picture have their hands raised.
Reach might mean you arrive somewhere after a journey, as in "she reached home after a long trip away".
It might also mean stretching out for something. The picture is of someone reaching for the sky. If you can't reach something no matter how far you stretch out your arms, it is said to be out of reach.
Reading is a way of converting written words into spoken words. You can either read out loud or read inside your head so noone else can hear you.
People who can't see can still read books. There are special books made for blind people that have patterns of small bumps instead of letters. This way of writing is called braille.
Something recedes when it moves away from something else. After a flood, the flood waters gradually recede back to where they were. The man in the picture has a receding hairline, which means his hairline is moving away from where it once was.
Something reflects light if it is shiny enough that the light hits it and bounces back off it. The man in the picture has sunglasses that reflect light.
