A reaction X <---> Y occcurs in a closed vessel. When it reaches equilibrium at temperature T, the number of molecules changing from X to Y is equal to the number of molecules changing from Y to X.

True. By definition.
" a state of balance between opposing forces or actions that is either static (as in a body acted on by forces whose resultant is zero) or dynamic (as in a reversible chemical reaction when the rates of reaction in both directions are equal)"

True. The rate at which the forward and reverse reactions is equal at equilibrium. This means that the number of reactant particles forming the products is balanced out by the number of product molecules reacting to form the reactants.
