As AWOL says, the answer is yes.

Please post an example of your problem

If it is not declared in the initializer part of the for loop, then yes.

byte i;
for (i = 0; i < 10; i++)
{
  Serial.println(i);
}
Serial.println(i);

Think of braces as boudaries of a box. Think of nested boxes.
Then whatever variable is defined outside a nested box is visible inside.

Example

for (int i=0;i<10,i++) 
  {
  byte a = 6;
  int j = i+1;
  while (j != 7) 
    { 
      // All these variables are known here
     int k = j+1;
    }
  // k is not visible here
  }
