Hi Dear, I believe all your quries might have been resolved already with assistance of @tajammal84.
You might be having a different point of view but in my consideration your garage is the first look of your home therefore do not go for badal it is cheap in price but chep in quality as well shinning will fade away in few months so better to go at least with China verona which is creamy type color, 1' x 1' size is fine but never ever go for kachra.
As regard indoor tiles we prefer imported ones at least chinese due to their finishing is better than local ones and most preferable size i like personally is 32"x 32" pls share your area so i can further assist you regarding availability of stuff near you.
Anything else can be asked without any hesitation
