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.
If the wiring diagram calls for it,yes.
You have a 3 way switch. Your black wire is the hot wire. Your green wire is the ground wire. Your red and white wires go to the light and other switch. You should have gotten a wiring diagram with your switch.
You have to pull a new wire. There is no way to do it with the existing wire, at least no way you should do it and be in code.
That depends on where the other end of the wire goes.
The two way switches work in pairs. We find most of them in our houses where the light bulb can be operated by two switches each at the far end to the other. Each switch consists of three terminals two of which are connected. When one switch is open and the other is closed then the bulb glows and viceversa

You will come off the battery + side with a wire to a fuse, from the fuse to a switch, switch to the light, the other wire from the light goes to ground. Protect the wire from the battery all the way to the light for wear. If you have trouble, or need more info let me know.

wire each switch to each light...
You don't. You use a pair of two-way switches ('three-way switches' in US/Canada).
If there are three current carrying conductors terminated on the switch you want to replace, then you can not use the new switch at this location. What it sounds like is the existing switch is part of a three way light switching circuit. Check online for images of "wiring of three way switching systems" and you will see what I mean.A regular light switch will only have two termination points on the switch. This type of switch could be a direct substitute for the interval timer switch, as both have only two terminal points.The only way that you could use the new switch in this circuit is to cut in a new junction box for the new switch adjacent to one of the existing light switch boxes. One end of the circuit would use the new switch for opening the incoming "hot" conductor or at the other end of the circuit, the new switch would open the conductor that goes to the light (load). If this method is used the existing switches will not be used for controlling the light and must be in a position so that the light will be always in the on position.If the three way switching is not needed then the existing switches can be removed and the wiring in the boxes can be rewired to accommodate the new switch and the other box would be blanked off.
It's with the head light switch, turn it one way and they stay on longer, the other shorter..
No good way to answer this. A 3-way light switch has one wire coming to it, two wires run to the second switch and one back out of the second switch to the light. At any point, any one of the terminals may be "hot". The only one always hot is the first single terminal that is the power source.
yes like a hall light.
