Lower case "o" and "x" both have two lines of symmetry. Upper case letters with two lines of symmetry are: "O," "X," "H" and "I."

H,I,O,X Note that if you draw "O" as a perfect circle, it will have infinitely many lines of symmetry.

ALL letters have at least one line of rotational symmetry. However - if you mean reflective symmetry, the letters F, G, J, L, P, Q, R, S, & Z do not.
As with the Roman alphabet, which you may be familiar with it (since you are using it to read this answer), different letters have different symmetries.
Four. F, G, J, L
all letters have a line of symmetry
A, v, m, w, y, o, u, x, t, i, h,
