2-from COMP layer to INT2 layer (Blind)
3-from SOLDER layer to INT1 layer (Blind)

Re: 4 layer PCB using PCAD

from the main menu click (options) and then click (via style) ..
Add new via and click properties , then define each via and describe in which layers it will be exist ...Repeat these procedure for all kind of vias you have ....
then when you rout your file use these vias in its correct positions
