Yes, normal 0603 resistor can be used in RF up to some GHz; the lower the value the higher the frequency. However in the picture I can't see any 10k resistor.
Common dielectric types: COG/NPO, X7R/X5R, Z5U, Y5V
COG and NPO dielectrics have the best performance vs. temperature (they don't change much). X7R/X5R's have more variation over temp but are decent in some cases (coupling caps, etc). The rest are just horrible when considering them for inside a filter structure, DO NOT use them for any RF design other than maybe bulk power filtering... but I don't even use them for that.
