Most ceramic capacitors use a numbering scheme similar to the resistor color code. Usually, three numbers are given.
The first two numbers are significant figures, and the third is the base 10 multiplier, or number of zeroes to add onto the end.
With ceramic capacitors, the value you get is typically assumed to be in picofarads (pF, 10-12 Farads). For much larger capacitors, the value is sometimes given in micro-Farads (uF, 10-6 Farads).
For example, for a capacitor marked "154":
1: First sig. fig
5: Second sig. fig
4: multiply by 104 (add 4 zeroes)
Result: 150,000 pF
Now, you can divide by one million to get an answer in uF, if that is more comfortable for you to work with:
150,000 pF = 0.15 uF
Therefore, a capacitor marked 154 has a value of 0.15 uF.
This should get you started reading ceramic capacitor values. For more detail, see the "coding" section of the wikipedia article on ceramic capacitors.
A capacitor that does not have a designated + and - side. Electrolytic capacitors are usually polarized. Ceramic capacitors are not.
capacitors are classified on the basis of dielectric material used inside it. For example the electrolytic capacitor consist electrolyte as dielectric mica capacitor consist mica as dielectric between plates and ceramic capacitor consist ceramic as dielectric.
You can see if the capacitor charges and discharges with an ohmmeter. You can check the value of the capacitor if the multimeter has the facility. With an ESR meter you can establish the value of the capacitor while in circuit.

An ideal capacitor is characterized by a single constant value for its capacitance.
That depends on the value of the capacitor and other components in the circuit.
encoded capacitor value in picofarads:47, digits5, zeros following digits4700000 pF or 4.7 µF
ceramic capacitor does not simultaneously discharges instead it maintains stead flow of charges through it
yes ceramic can be replaced by polyester

A capacitor alone doesn't have a frequency. The combinationof a capacitor and an inductor (coil) has.-- Read the value of capacitance printed on the capacitor, or measure it. Call it ' C '.-- Read the value of inductance printed on the coil, or measure it. Call it ' L '.The resonant frequency of the combination of those two components isF = 1 / (2 pi) sqrt(L C)

The filter capacitor has inductance and is therefore not very responsive to short term transients, i.e. fast rising or falling current edges. The ceramic disk capacitor, on the other hand, has very little inductance, and therefore is very responsive to short term transients. It is normal "best practices" to connect a small ceramic disk capacitor at each IC's Vcc terminal while also using bulk capacitance in the power supply and at various other places. For the same reason, you want a ceramic disc at the main filter capacitor in the power supply.
