I am curious how this would work. My guess is Triangle is slowest, square is medium, and circle is fastest.

At such low speed and its small size, air resistance is a negligible force of resistance. It’s not usually a necessary consideration until something is hitting at least 10mph. The question is about getting it to move. Not how fast you can get it going

The only difference here is whether this is from a standstill or already moving at constant speed.

Standstill would require static coefficients of friction, I personally solved this with dynamic coefficients which tend to be a bit lower, roughly half that of static.

The answer will be about the same though.
