The only polygon with just acute angles is an acute angled triangle.
If its acute angles are different then it is not a regular polygon but if it has 3 equal acute angles of 60 degrees then it is a regular equilateral triangle
Parallelogram.
All triangles have at least two acute angles. Acute triangles have three. Rhomboids also have two acute angles.
Yes, a rhombus has two acute angles.
It could be any irregular polygon with 4 or more sides (and 4 or more angles).

yes
An acute triangle.
The only polygon with just acute angles is an acute angled triangle.
Any polygon can contain acute interior angles.
An acute polygon is one whose interior angles are all acute. Only a triangle can be an acute polygon.
If its acute angles are different then it is not a regular polygon but if it has 3 equal acute angles of 60 degrees then it is a regular equilateral triangle
A right angle triangle or an obtuse triangle
Parallelogram.
A right triangle.
Although a triangle must have at least two acute interior angles, a square has four interior right angles and no acute angles. And as regular polygons have increasing numbers of sides, their interior angles get larger.
