Q: Where can I get replacement lead?

Mr. Pen- Compass Lead, 100pcs Leads, 2mm Lead, Refills Compass for Geometry, Lead for Drawing Circle, Replacement Leads in Refill Tube, Math Compass Lead, Drafting Lead, Break Resistant Lead, Graphite https://www.amazon.com/dp/B07MJTYGFY/ref=cm_sw_r_cp_api_glt_fabc_D2GJ2V8Q0T6V9GWGFX44 These seem to fit the compass.

Q: Is there a pocket that holds rulers and protractor secure in lid so they don't fall out or have to be moved out of the way every time case is opened?

Your question indicates that you think the pieces are stored in the lid. They are not. They fit into the case but if you have the kit open and turn upside down, some may fall out. To remove the compass, you may need to move the protractor out of the case in order to remove the compass. It’s a very nice kit, but I keep a rubber band around the outside of the case to be sure it doesn’t pop open and the contents spill out.

Q: What is the unit of measurement? For example, some pictures show the rulers with both cm and inch measurements, while others show only cm measurements

Unjoo's geometry set has been upgraded，The measuring units of ruler inch and cm

Q: How wide of a circle can you create with the Compass?

If I remember correctly I think 12in diameter. .
