all works, except the first 0

char numero[10][7]={"1111110","0110000","1101101","1111001","0110011","1011011","1011111","1110000","1111111","1110011"};
byte puerto[14]={0,1,2,3,4,5,6,7,8,9,10,11,12,13};

void setup() {
 byte i;
 for (i=0; i<=14; i++)
   pinMode(i, OUTPUT);
}

void loop() {
   segdigito();
 }
 

void pridigito(){
   byte i=0;
   byte p=0;
 for(p=0;p<10;p++)
 {
   for(i=0;i<7;i++){
     if(numero[p][i]=='1') digitalWrite(puerto[i], HIGH);
     else digitalWrite(puerto[i], LOW);
   }
   delay(100);
}

}

 void segdigito(){
  byte i,p;
   for(p=0;p<10;p++)
 {
 for(i=7;i<14;i++){
     if(numero[p][i]=='1') digitalWrite(puerto[i], HIGH);
     else digitalWrite(puerto[i], LOW);
   }
   pridigito();
   
 }
 }

when you do

char numero[10][7]={"1111110","0110000","1101101","1111001","0110011","1011011","1011111","1110000","1111111","1110011"};

the "1111110" (and others) are not stored on 7 bytes. this is a cString so there is a trailing '\0' that you don't see added by the compiler

If I were you I would check those indexes...

for(i=[color=red]7;i<14[/color];i++){
     if(numero[p][color=red][ i][/color]=='1') digitalWrite(puerto[ i], HIGH);
     else digitalWrite(puerto[ i], LOW);
   }

you could just use const char * numero[] = {"1111110","0110000","1101101","1111001","0110011","1011011","1011111","1110000","1111111","1110011"};

What do you suppose that '1' - '0' is? What do you suppose that '0' - '0' is?

Instead of the 4 line if statement to determine whether to set the pin HIGH or LOW, and to actually do it:

     digitalWrite(puerto[i], numero[p][i] - '0');

all works, except the first 0

You need to explain that, in a lot more detail.

Your blocks of characters are 7 characters long. Why are you using indexes 7 through 13?!? Did you intend to use "numero[p][i-7]"?

char numero[10][7]={"1111110","0110000","1101101","1111001","0110011","1011011","1011111","1110000","1111111","1110011"};

 for(i=7;i<14;i++){
     if(numero[p][i]=='1')
        digitalWrite(puerto[i], HIGH);
     else 
        digitalWrite(puerto[i], LOW);
   }
