The matching of power ratings between amp and speakers is not a precise science.
Loudspeaker distortion is not as unpleasant as amplifier clipping so I prefer to err on the side of having a beefier amp (within reason). Any modern amp will have protection circuitry that cuts the output in the event of an internal fault, so the chances of the speakers bursting into flames is not worth worrying about.

Ok so I can have a more powerful amp than speakers but what about if the speakers are more powerful than the amp - would that damage the amp. I any case the equipment is either 5 10 or 20 W

No, you won’t damage the amplifier by driving speakers rated for a higher power, surprisingly the risk is actually to the speakers! If you don’t get enough volume there is a temptation that you’ll turn the amplifier up to the point where it distorts, this generates higher frequencies and can create enough to burn out the tweeter. You’d need to be a bit cloth-eared to do this, but it happens quite often.
