Two or three.
Depends. Most of the time the angles are acute or obtuse
An arrowhead typically has two equal angles. The two angles are formed by the two sides of the arrowhead meeting at the tip. These angles are typically acute angles, each measuring less than 90 degrees.

The arrowhead has zero right angles.
it has no acute angles
It depends on they type of arrowhead you have. If it is a arrowhead in the shape of a directional arrow, there are no obtuse angles. The most possible obtuse angles is 1.

The 'classic' arrow-head shape has 7 angles.
A cone has no acute angles because a cone is a 3D shape and not a 2D.
An arrowhead shape typically consists of a triangle or a series of angles that form a pointed end. In a simple triangular arrowhead, the internal angles sum to 180 degrees. If the arrowhead includes additional angles or extensions, the total degrees could vary, but the fundamental triangular portion remains 180 degrees.
There are many possible shapes with two acute angles.

A heart is not technically a geometric shape, but it depends on how you draw a heart. If the angles measure less than 90 degrees, they are acute angles.
I'm not sure but i think it might be 4 acute angles but i suggest you try a more accurate site.
