I am asking only about the item labelled F . Third diagram is resultant force. Second diagram is equilibrium. first diagram is confusing?

First diagram is poorly sketched and was probably meant to show the x and y components of F, but F does not have the requisite length for $F = F_x+F_y$. Second diagram is $F + F_x + F_y = 0$, so yes, equilibrium. Last diagram is $F = F_x  F_y$
