Yes, sometimes. Two acute turns make an acute turn only if their sum is still less than a right angle; for example, 30° + 40° = 70° (acute). Otherwise, they may total a right or obtuse angle.

CBSE Class 5 Maths-Mela Chapter 3 Angles as Turns solutions
Two acute turns (each <90°) can combine to make another acute turn if their total is less than 90°. Example: 30° + 40° = 70° (still acute). But if they sum to 90°, that’s a right angle; if they exceed 90° but are <180°, that’s obtuse. The fan-and-straw activities invite exactly this exploration.
