One has "103" printed on it,

That is a 0.01uF - numbers are the same as resistor codes, the last digit being the number of zeros and the value is in pF so you have a 10000pF capacitor which is 10nF or 0.01uF.

The second type has the following printed across 3 lines: "Y5P", "471K", "KCK"

Y5P is the type of dielectric, the value is the 471K like before only the K adds another three zeros so the value is 470000pF or 470nF or 0.47uF. Don't know about the KCK

- the third has two lines, ".0015K", "X5F"

Same again X5F is the dielectric but the number is a bit more vague but I would guess it indicates 15nF

Not sure about the other, that probably shows my age.
