Sheep, the same as your character and other mobs, can only jump one block. A one block high jump is enough to get around the basic environment of minecraft. But they can glitch over fences but this may be patched soon/may have already been patched.
two blocks, but they can also climb walls.
i am not sure but i thinck about one meter
no
yes all sheep can jump on the spot and anywhere else.
Generally sheep have poor eyesight. They will stare at area's they detect movement to see if that movement is a threat to them. They will move together for safety if they feel something may be stalking them.
Wheat!
To find pink sheep in Minecraft, you will need to go to a grassy area to look because peaceful mobs spawn on grass and I have found a pink sheep which is 1/100 likely to find pink sheep but Minecraft wiki doesn't tell you about pink sheep.<(0_0<)(>0_0)>
Give each sheep you want to breed wheat.
