Yes, pentagons can have right angles. A pentagon is defined as a polygon with five sides, and its angles can vary. While a regular pentagon has equal angles that do not include right angles, an irregular pentagon can have one or more right angles depending on its specific shape and configuration.
It depends on how they are classified. They can have 1 to 4 acute angles, they can have 1 to 4 right angles, they can have 1 to 5 obtuse angles. The individual values of the angles will generate different pentagons. They can be regular or irregular. They can be convex or concave.
All pentagons have five sides.
Yes providing that they are regular 5 sided pentagons otherwise no if they are irregular pentagons

No, pentagons to not have right angles.
no, pentagons don't have parallel sides or right angles.

All pentagons have five sides.
Yes there are two different pentagons with two right angles next to each other and more with 2 right angles not next to each other.
Yes providing that they are regular 5 sided pentagons otherwise no if they are irregular pentagons
Pentagons in normal (Euclidean) geometry can have at most three right angles, and the other two will be obtuse.However, in hyperbolic geometry, it is possible to construct a pentagon with 5 right angles, which is called a rectapentagon.

No, it is true of all pentagons.
Regular pentagons do.
