Some of these don't look like checkboxes at all, and wouldn't trigger any indication that they could be changed. For example, if I saw number 44 next to a line of text, I'd think "that must be something not available for some reason" rather than "I could click that to choose it".
Same with 50 and 26 (that's a stop sign!) - they look like bullet points.
Some of the others are pretty nice though!
