When microphone near the sound speaker it make noise.why?

When a microphone is placed near a sound speaker, it can pick up the sound output from the speaker, causing feedback loop. The sound that comes out of the speaker is captured by the microphone, sent back through the system and played through the speaker again, resulting in a continuous loop of sound amplification, which leads to the noise you hear.

How can a speaker work with holes in it?

It can work, but it will not sound good. Any deformations of the cone will "color" the sound, which will sound muddy and not clear. Eventually the speaker will die due to the voice coil dragging in the magnet because the speaker isn't moving correctly. If you have a speaker with a hole in it you should replace it.
