Yes. Draw the letter H on a piece of paper and turn it upside down. You'll notice that it still looks like an H. It does not have 90 degree (or 270 degree) rotational symmetry, though - if you turn it sideways, it looks like a weird elongated I.

When you rotate it around a point found in the middle of the figure 180 degrees. For example, H does have rotational symmetry however, E doesn't
Assuming "rotational symmetry" means looks identical when rotated 180 degrees. H I N O S X Z
H
A lower-case 'h' has rotational symmetry. An upper-case 'H' also has reflective symmetry.
Yes, it does.
