How about upgrading freewheel to 9 from 6?
#1
I measured dropout 138 mm, but I only have 6 sprocket freewheel.
According to this table 135 is enough for 9 sprocket freewheel (cassette):

What do i need to convert freewheel to cassette? Will I need new derailleur?

There are no 9 speed freewheels. And likely you have a freewheel, as there were very few 6 speed cassettes. Cheapest: purchase a new rear wheel, new cassette, new shifter, new derailluer and new cable - figure between $100- for very low end stuff, to around $500- for good stuff, and $1000- for the very good stuff.

I doubt that you have 138mm between the dropouts, maybe to the outside of the drop outs.

car5car. Your ruler appears to be backwards in this picture. You want to measure the space between the dropouts.

Left side of the ruler has mm scale.
