Batteries are normally specified in ampere hours. A 12 v battery could be specified as 14 A-h or 14 ampere-hours, which means 14 amps for 1 hour, or 1.4 amps for 10 hours. In other words it produces less current for a longer time.
A 9 watt bulb takes ¾ amp in theory, so it should last 14/¾ hours on that battery, that is 14 x 4 / 3 hours, 18 hours. Or two of the same bulbs for 9 hours, etc.
1.5 Amperes, or Amps.
cca is 'cold cranking amps' in other words how many amperes can a given battery supply to crank a cold car engine. A good battery can give 400 amps for cold cranking.
yes! connect all the bulbs in parallel.. i.e. battery positive terminal will be tied to one side terminals of bulb and other terminal to the other. but it will result in less power delivered.. and fast battery usage..

It depends on the battery's voltage. Such a battery's capacity is given in ampere-hours, not amperes. An 850 amp-hour 12 volt battery can theoretically operate a 12 volt motor for about 12 minutes but in practice it's probably, maybe a lot less, since the motor will probably stop as the battery nears its depletion.
The number of amperes is unrelated to the voltage. The maximum amount of current (in amperes) that you can take from the battery depends on the exact build of the battery.

Check the fuse which protects the battery circuit. It should be with many amperes on it.
The apmeres depend on the resistance of the circuit. The battery will be a certain voltage, and dividing the voltage by the resistance gives you amperes. V = I*R
it takes 1 C type battery <><><> That answer is not really very helpful because the question doesn't say what the voltage of the light bulbs is! This question cannot be answered without knowing at least the voltage of the light bulbs and also the voltage of the battery that is being asked about.
A 300 ampere-hour battery can supply 300 amperes for somewhat less, sometimes substantially less, than one hour. It might not even be rated to provide 300 amperes at all. It depends on the battery. The reason for this is that ampere-hour ratings are, by definition, normalized to an eight-hour rate. This means that you can pull 300/8, or 37.5 amperes from that battery for 8 hours. That is the reference point. If you were, for instance, to pull 18.75 amperes, you would expect the battery to last somewhat longer than 16 hours, and if you pulled 75 amperes, you would expect the to last somewhat less than 4 hours, both from a full charge, and both from a recently equalized state. You need to check the published discharge curve for the batter to know for sure.

This question cannot be answered properly without knowing at least the voltage of the light bulbs that are being asked about. When you know the bulbs' voltages then you will have to consider whether to wire them in series or in parallel to match the voltage available from the battery.
The human beings have the ability to tolerate about 0.007 Amperes.
