The label 60 watts bulb max is referring to each individual bulb, not the total in the light fixture.
The total wattage of the light fixture with 3 60-watt bulbs is 180 watts (3 bulbs x 60 watts per bulb).
The amperage that a chandelier draws is based on the amount of bulbs and the wattage of the bulbs used in the fixture. Count the amount of bulbs and multiply that number by the wattage of the bulbs. Take this total wattage and use this formula. I = W/E. Amps = Watts/ Volts.
If you can tell me the resistance across the bulb, I can tell you the total wattage. Watt = amps x volts. I (amps) = E (volts 2.5)/ R (resistance in ohms). Calculate for amps draw on one lamp and then times 300 will give you total amperage. Take this value times total voltage and it will give you total wattage.
The number of bulbs a dimmer switch can control depends on the wattage rating of the dimmer switch and the individual bulbs. Consult the dimmer switch's specifications to determine the maximum total wattage it can handle, and then ensure the combined wattage of the bulbs you intend to use does not exceed this limit.
Two thoughts here, one the fixture should be rated at the maximum wattage allowed for the socket the bulb screws into. A label should state "maximum wattage allowed". To do a calculation Watts = Amps x Volts. Amps = Watts/Volts. 5 x 60 watts = 300 watts. 300/120 = 2.5 amps. The electrical code only rates down to #14 wire which is rated at 15 amps. From here you have to make the decision.
Three 20 watts bulbs will consume 60 watts.

The recommended wattage for 25 watt light bulbs in this fixture is 25 watts.

The usual criteria is that the larger the envelope size of the lamp the larger the wattage of the lamp. The terminology of "big bulbs" suggests that the lamp could be in the range of 400 watts.

You can use a three way bulb in a one way socket. I believe the default wattage will be the middle one. E.g., a 30-70-100 watt three way will default to 70 watts in a one way lamp or socket.
The number of watts a lamp uses when turned on depends on the type and wattage of the bulb. Common incandescent bulbs typically range from 40 to 100 watts, while LED bulbs are more energy-efficient and can range from 4 to 20 watts.
