Independent Fade LED and Blink without Delay

Hello,

New to the Forum and probably not doing this right, although I did search and attempted multiple solutions, to no avail.

What I am trying to achieve, coding wise, is the following:

1 Blinking LED
2 Steady LED's
2 Independently Fading LED's

eventually I need to add 4 more steady LED's but trying to get this first.

My code currently is as follows: the Fading LED's (3 & 6) are fading to close together and I would like to offset that but I can not seem to figure it out.

int value, value2, value3 ;
int ledpin = 3;                           // light connected to digital pin 3
int ledpin2 = 6;                           // light connected to digital pin 6
int ledpin3 = 7;                           // light connected to digital pin 7
long time=0
;

int periode = 1000;
int displace = 100;

void setup() 
{ 
   pinMode(4,OUTPUT);
     pinMode(5,OUTPUT);
} 

void loop() 
{ 
digitalWrite(4, HIGH);
  digitalWrite(5, HIGH);
  
 time = millis();
 value = 128+127*cos(2*PI/periode*time);
 value2 = 128+127*cos(2*PI/periode*(displace-time));
 value3 = 128+127*cos(2*PI/periode*(displace-time));
 analogWrite(ledpin, value);           // sets the value (range from 0 to 255) 
 analogWrite(ledpin2, value2);           // sets the value (range from 0 to 255)
 analogWrite(ledpin3, value3);           // sets the value (range from 0 to 255) 
}
