no!
First you need to decide what you are trying to accomplish. You can wire the Timer switch in series with or parallel to the 3-way switches. If in series then the 3-way switch function would depend on the timer state. If the Timer switch was ON then the 3-way switch could turn the connected device ON or OFF from either location. If the Timer switch were OFF the device would be OFF no matter what you did with 3-way switches. To wire in this fashion put the timer between the supply and the input to the switches. If the Timer is in parallel then if the Timer is ON it doesn't matter what you do with the 3-way switch, the device will be ON as long as the Timer is ON. If the Timer is OFF then the 3-way switches will work in their normal fashion. To wire in parallel connect the supply to one side of the Timer and the device to the other.
to wire a lamp to be controlled from three places you need two three way switches and one four way switch. the two traveller wires that would normally run between the two three way switches must be connected to the terminals of the four way switch
One. A typical "two way" ON-OFF light switch is a Single Pole Single Throw (SPST) switch with two terminals. It is wired in series with the fixture: that is, the power circuit is routed from the breaker to one side of the switch. The other side of the switch is connected to the "phase" or "power" terminal of the fixture. In a 115VAC single phase circuit, the other terminal of the fixture is connected to neutral. A "three way" switch circuit consists of two switches in different locations, each of which is a Single Pole Double Throw (SPDT) switch with three terminals. A typical use would have one switch at the top and the other at the bottom of a set of stairs. For the sake of clarity, we can label the "common" terminal on a SPDT switch the "C" terminal. This terminal is internally connected to one of the other two terminals, call them "A" and "B", depending of the position of the switch. A three way switch is connected with the circuit breaker connected to the "C" terminal on either switch. Conductors connect the "A" terminal on one switch the the "A" terminal on the other switch and the "B" terminal on one switch the the "B" terminal on the other switch. The remaining "C" terminal is connected to the "phase" or "power" terminal of the fixture. The other terminal of the fixture is connected to neutral. Note that, in either case, there is no neutral wire connected to the switch. Ground conductors do connect to the chassis of the switch box and the fixture, but they do not carry current and do not affect the operation of the circuit.
Voltage would be that of 1 cell.
No. A double pole switch would be a switch that switches 2 different loads simultaneously. 3-way switches (and 4-way switches if more than 2 are used) are what are used for controlling a light from multiple locations. While a typical single pole switch simply opens or closes a single contact, a 3-way switch provides a path from a contact point to, let's say, point A or point B. Points A and B from the first 3-way switch are connected to points A and B of the second 3-way switch and then the common contact point of the second switch is connected to your light. When more than 2 switches are desired, you can use any number of 4-way switches between the 3-way switches, but the 3-way switches MUST be on the ends of the circuit.
No it doesn't
For a standard switch, it doesn't matter. If it's a 3 way switch, "hot" is connected to the "common" connection.
Does not matter!
because it is the other way round...it is connected to the veinrather than the artery.

You will actually need 2 3-way switches to control something from two locations. The first switch will receive the power, while the other will go directly to the load being controlled. The switch getting power will have the hot lead connected to the common terminal. The other switch will have its common terminal connected to the hot lead going to the load. Two "travellers" will be connected between the other terminals on the switches. They will be connected switch-to-switch. And don't forget that your neutral coming from the power feed will be connected to the load. Also don't forget to connect ground wires.
No, it's the other way round. Matter is what CAUSES gravity.

The round manhole cannot fall into the hole no matter which way you turn it.
