anything that has an angle measure of greater than zero and less than 90
No, It is not possible to have a quadrilatera with four acute angles because the addition of four angles for quadrilateral = 360 & acute angle is less than 90 degree
Your head
An acute angle is an angle that measures less than 90 degrees. See the related link, "Acute Angle Pictures" for a diagram of some acute angles.
Spherical triangles as on the earth's surface.
A pizza slice
some triangles and rhombuses. trapoziods do not have acute angles it has obtuse angles. :)

Just about any shape that isn't a circle can have two or more acute angles. But with some of them, you need to make them have acute angles.
Some of them do.
Go to google.com/images and search "obtuse isosceles triangle", that should get you some good examples.

5. all acute. and then some straight angles.
equilateral triangle, acute triangle, some isosceles and scalene triangles
Yes . Some might have acute angles . Most likely right angles .
All triangles have 3 acute angles because 60+60+60= 180 which is correct for a normal triangle so yes
Yes. Any triangle (in the standard Euclidian geometry) has at least 2 angles; some have 3.
