2.
A kernel of popcorn that did not pop when heated.
There's a fine art to timing microwave popcorn, where you avoid burning the ones that did pop at the expense of leaving some old maids. Why 'old maid', you ask? They're the ones left behind that haven't been 'popped'.

3.
a woman who has passed the age at which women typically marry (for the first time) and/or have children without doing either (derogatory term; "maid" is short for "maiden" meaning "virgin", and stems from the former presumption that a woman who had neither married nor had children was a virgin)
