Resolution & Pixel
Is it possible to have number of same images but different resolution in the same canvas? I tried but it does not work. Resolution of all images default to resolution of last image.

Pixel is a computer unit, inch is a physical unit. If resolotion say 300 ppi. Have we to assume that there are 300 pixels in one inch length of the image printout? If so, ppi mearly creates a relation between computer unit & physical length.
Is there any relation between ppi & dpi?
You've got it 🙂
ppi (literally pixels per inch) is the unit used in Photoshop, and other imaging software, to convert pixels into a physical size on paper. There is a lesser used but equally valid ppcm (pixels per cm) for those working in metric.
dpi (dots per inch) is often, incorrectly, used interchangeably with ppi. But dpi is a different measure and refers to the dots used by the printer to make up the individual pixels on paper. So, for example, you might see an inkjet printer which lays down 2880 dpi. That does not mean the printer can print 2880 ppi.
You might also come across lpi (lines per inch) which refers to the screen used in some printing techniques when printing to a physical media.
