Unsure AA play

I'm use to limit, so getting my feet wet in the NL ring arena. This is at a .10NL table. I'm only going to detail up to the flop for now, that's where I'm curious if I'm playing right.

I am SB, dealt AA. I have about $6.50, seems average for the table.

5 people limp in. I raise to .50. Two folds, three calls.

Flop is J99. I am first up, I should...... ?
(I'll go further into what happens next after)
