Converting an SMD resistor PCB into wires and film resistors
Yes, you would get R1+R2+R3+R4+R5 with no switches pressed, and almost a short with just switch 1 pressed, just R1 with SW2 pressed etc. There is a kind of priority in this arrangement- only the lowest number switch can be detected if more than one is pressed.  

You can buy resistor values R1..R5 and wire them to switches. You have not provided the values- if they are standard values you can buy those values, if not you might have to make them up with a couple standard values for one resistor. 

I can't really help you with 'wiring it up', it's just as the schematic shows. One side of all the switches is connected together and the other sides go to various spots in the series string of resistors.
