I'll have a stab at answering these.
Throwing Weapons:SomeGuy wrote:
Q1. If warrior of rohan with a throwing weapon in the movement phase decides to charge and throw his spear at his target, suffering the penalty to shoot value and so on, if he hits and kills his target and is now free to finish his movement, deciding to charge a second enemy can he throw the spear again, or is it just once in the movement.
Just once per movement phase.

Q2. Again if a warrior of rohan with a throwing weapon chooses to charge and throw his spear at an enemy model, but this time fails to secure a kill, he now must finish the charge, engaging that model in combat, but if a second warrior of rohan with throwing weapon wanted to charge that same enemy who is now in combat, can the warrior of rohan throw his spear at the target, or is this disallowed cause the enemy model is now in base contact with the allied warrior who failed his throwing spear charge earlier? and in a reverse situation i would assume an evil warrior can throw his weapon still on the charge but follows the same rules for shooting into combat, that he might hit his ally model in the fight?
Once engaged, a good model would be unable to throw a spear when moving into combat, however, as you say an evil model would be able to throw into a combat with the normal in the ways that would come from shooting into a combat.

Q3. Final question( i think for now regarding Throwing Weapons), If the warrior of rohan charges, throws his spear, and kills the enemy model but chooses not charge any other model that round, assuming he hasn't been charged come the shooting phase can he opt then throw his spear again in this phase, and if yes does he still suffer the shooting penalty for moving?
I believe the ruling is; as long as the warrior is unengaged by the shooting phase he may shoot again, but would suffer a movement penalty.
Cavalry Charges:SomeGuy wrote:
Q1. If the cavalry model charges an enemy on foot but is then countered charged by a second enemy, also on foot does he still retain his charge bonus attacks.
Yes, this is correct the cavalry model still gains the knock to the ground and the bonus attacks.
SomeGuy wrote:
Q2. similiar to question one but in this situation the cavalry model has been counter charged but is now taken out of the original fight with the model he charged, in this situation does he still retain both charge bonus, seen as he no longer fighting the model he charged.
Yes as he gains the bonuses so long as he has charged into an infantry model that turn. (This can be negated by moving another cavalry model into the combat.)

Q3 if the cavalry model is charged to begin with, not having moved yet, by an infantry model, he doesnt gain the +1 attack bonus, but despite being charged he wins the fight, does he still knock the enemy to the ground?
No. he needs to have charged himself to gain any of the bonuses from charging.
Control ZonesSomeGuy wrote:
If i have a wall of uruks with shields supported by pikes, their control zones would inevitably overlapping, so if i wanted to charge and enemy in the centre of the shield wall would i have to essentially charge two enemies because I'm technically enter the two models control zones,
As soon as you enter a control zone you disregard any other control zones that you may enter, as long as your base does not touch another models then you are considered to be in a 1on1 combat.
Unit Name UpgradesSomeGuy wrote:
If rider of rohan is upgraded to a redshield by erkenbrand giving him a fight value of 4, when that redshields mount is killed and he finds himself on foot, does he lose the fight value bonus or retain it
He retains it as he is now just a dismounted Redshield.
