so guys how could i cut these acrylics using jigsaw like i said cant afford any other tools or if you any other cheap recommendation plz do let me know

 

Mirror acrylic is usually extruded, so a jigsaw will melt it. Your best bet is to file it.

 

I've found that it is better to use a blade with larger teeths rather than fine. The fine teeth one cuts slower and removes smaller pieces from the acrylic thus heating it up more -> melting. Depending on the thickness of the material there must be a sweet spot on what kind of teeth size and teeth spacing is ideal but for me almost any blade meant for wood has worked great...
