Will this code work for Arudino.

Well first of all, try compiling it. It doesn't compile at all.

There are several issues.

Firstly, you cannot declare a struct like this:

typedef struct { 
byte servoValue; 
byte servoVal; 
int iFinger; 
} DEFAULT servo[MAX_FINGER];

Try this instead:

typedef struct { 
  byte servoValue; 
  byte servoVal; 
  int iFinger; 
} SERVO; 

SERVO servo[MAX_FINGER];

Notice that DEFAULT cannot be used as it is a #define in another part of the Arduino core (part of analogRead()). Secondly you can't create a struct at the same time as you define it. You have to seperate the creation of an object from the creation of a type.

For the servo side, you forgot this line:

#include <Servo.h>

Which goes at the very top and includes the servo library.

There is one place in your code where you have used a '-' sign instead of an '=' sign. In another place you missed a ')'.

The next thing to point out is that if you format the code correctly (autoformat helps), then it is easier to read.

After fixing those, you get this:
Code1:

#include <Servo.h>


#define MAX_FINGER 5 
// #include 
// create servo object to control a servo 
typedef struct { 
  Servo myservo; 
  byte servoAng; 
} SERVO;

SERVO servo[MAX_FINGER]; 

void setup() { 
  Serial.begin(9600); 
  int i = 0; 
  for (i = 0; i < MAX_FINGER; i++) { 
    servo[i].myservo.attach(i + 2); 
  } 
} 

void loop() { 
  if(Serial.available() >=5) { 
    int i = 0; 
    for (i = 0; i < MAX_FINGER; i++) { 
      servo[i].servoAng = Serial.read(); 
      servo[i].myservo.write( servo[i].servoAng ); 
    } 
    // Send the servo to the position read... (note: you get to make this happen) 
  } 
}

Code2:

#define MAX_FINGER 5 
typedef struct { 
  byte servoValue; 
  byte servoVal; 
  int iFinger; 
} SERVO; 

SERVO servo[MAX_FINGER]; 
const int ciDefault[] = { 200, 460};

void setup() { 
  Serial.begin(9600); 
} 
void init_default() { 
  int i = 0; 
  for (i = 0; i < MAX_FINGER; i++) { 
    servo[i].iFinger = analogRead(i); 
    if (servo[i].iFinger < ciDefault[0]) servo[i].iFinger = ciDefault[0]; 
    else if (servo[i].iFinger > ciDefault[1]) servo[i].iFinger = ciDefault[1]; 
    servo[i].servoVal = map(servo[i].iFinger, 460, 200, 255, 0); 
    Serial.print(servo[i].servoVal); 
  } 
}

void loop() { 
  init_default(); 
  delay(100); 
}

Which compiles. Whether it works or not, I haven't looked through it to see (it is 1am here and I am off to bed).
