The energy required for the deprotonation increases for the hydroxyl group and even more so for the carboxyl group. However, the deprotonation at the H2 and H3 sites is almost as likely to occur, the difference in energy being very small.
Malic acid is a dicarboxylic acid, meaning it has two carboxyl groups. Lactic acid is a monocarboxylic acid with, as you might've guessed, a single carboxyl group.
