It depends on what kind of fence you wish to put up. For example, an electrified barbed wire and steel post fence would only require about three posts. But a wood plank and wood post fence would require about five or six.
Delbert can paint the fence in 11 hours so in 1 hour Delbert paints 1/11 of a fence. Similarly, in 1 hour Dorothy paints 1/12 of a fence. So together, in 1 hour they paint 1/11 + 1/12 = 12/132 + 11/132 = 23/132 of a fence. So to paint the fence together they would need 1 / (23/132) = 132/23 hours = 5.74 hours
There are four quarts in a gallon, so five gallons of paint would be equal to 20 quarts.

About 6-8 gallons, depending how you paint and what the surface is.
Alkali paint.
If the fence is their property, and not yours; you would need their consent to make any modification to it.
If 169 is floor area, then you are talking about roughly 430 square feet of wall. I would paint that with a bit less than 2 gallons.
You can buy cheap paint for about 22 a gallon. Depends what you want to paint and how long you want it to last.
