1. 2nd because if we count from left to right each column there will be 2cubes, 3cubes and a cube, which means the 2nd one olny makes sense 2. 4th because from the original view and from top to bottom the circles were ordered like red, yellow, green and orange. the red one is the tiniest so it means red one should be inside the yellow one and ... to the green is the largest one. 3. 3rd because there are 4 columns (from left to right is 1,3,1,2 which means only 3rd one makes sense) 4. 3rd because from the original view and from top to bottom the circles were ordered like green, red,green,yellow and cyan. the first green one is the tiniest, which means it should be inside the red one and ... to the cyan is the largest one. 5. 1st because theres a lack of a cube in the left bottom and in the middle.

my explanation may not be reasonable, hope you understand.
