I need the name or number of the bricks that the minifigures are on

Question

I need the name of grey pieces that the minifigures are standing on.

Answer 1

It's not a very clear picture, but I suspect it's not a single part, but rather made from the following 3 parts (stacked on top of each other in top to bottom order) :

• 1x Light Bluish Gray Slope, Curved 2 x 2 x 2/3

• 1x Light Bluish Gray Plate, Modified 2 x 2 x 2/3 with 2 Studs on Side

• 1x Light Bluish Gray Brick 2 x 2

And attached onto a base plate, resulting in (color added to show the separate parts) :
