I need to attach a 2x2 gatepost, with a flange at the bottom, to my 4"
concrete sidewalk.

What is the best way of bolting the flange (4 holes) to the concrete? I
have a 1/2" hammer drill with a 9/16" concrete drill bit.

How do I proceed from here? Can I just drill 4 holes in the concrete with
my 9/16 bit and then insert some kind of a fastener in the holes? What
kind?

what's going to be the side pressure on these? they have expanding bolts
that you drill holes, insert bolts, and wrench them to get them to expand.
