You already answered the question. Both cars are traveling at 70kmph, which is the same velocity.

Speed - but NOT velocity.
Using the equation of motion v = u + at. v-the final velocity, u - initial velocity a- acceleration and t-the time.
Velocity is direction and speed so the vehicle do not have the same velocity
No. Velocity is a vector, so it has both a magnitude and a direction. If the velocity of your car was heading in the positive direction, then the other car is moving in the negative direction. The velocities are NOT the same!
Acceleration = Change in Velocity / Change in Time a = (Final Velocity - Initial Velocity) / (Final Time - Initial Time) = (55-0)/(5-0) = 55/5 a = 11 m/s^2
Yes, two cars moving with the same velocity can collide if their paths intersect or if one fails to stop in time to avoid hitting the other. Velocity only describes the speed and direction of an object's motion, not its position. So, the cars can still collide if they have the same velocity.
Both cars would have the same momentum since momentum depends on both mass and velocity, and in this case, the cars have the same velocity and mass. So, the momentum of both cars would be equal.
