All are 1/8 Watt. Resistor values can be found here:

Inspect traces in red circles, they look corroded as well. And possible under the socket of U20.

If you mean the 4 resistors just above U20 (R35-R38), they are 10K. The colors are faded but used to be Black-Brown-Orange. With a multimeter you can measure the resistors. It will show close to 10.000 Ohm.
it is ok to use 1/4 Watt.
