DS18B20 Scrambled LCD HELP!

  {
    if (minTemp1 == -127) lcd.print("Error");

    else{
      lcd.print(minTemp1w,1);
      lcd.setCursor(7,3);
      lcd.print(minTemp1d,0);
    }
  }

You have a very strange syntax for if clauses. Usually the curly braces around the whole block is not necessary but it would be easier to read if you put the "lcd.print("Error");" into such a code block.

Remove the pin defines as they seem to be wrong.

Remove the

#include "Wire.h"

It's not used.

I also didn't find out why you define three float values for every output value.

float nowTemp2;
float nowTemp2w;
float nowTemp2d;

It's interesting that on both scrambled displays a text fragment of "Error" is visible. Try to fix the above issues and post the results your get.
