Yes you can, as long as the four angles (obviously three of which will be less than 90 degrees) end up with a sum of 360 degrees, meaning there will have to be at least one obtuse angle in a non-square quadrilateral.

No, a quadrilateral can't have three acute angles and one right angle. The angles of a quadrilateral must total 360. The three other angles of a quadrilateral with one right angle would then have to total 270 degrees. If all three were acute (less than 90 degrees), they could not total 270.
noA 4th angle would have to be obtuse, because the acute angles could not sustain a quadrilateral.
A rhombus has 2 opposite acute angles and 2 opposite obtuse angles
There can be 4 different acute angles in an irregular 4 sided quadrilateral that all add up to 360 degrees.
Any irregular polygon can have an acute angle. A regular triangle (equilateral) has three acute angles. All other triangles must have at least two acute angles. A quadrilateral, other than a rectangle (or square), must have at least one.
