Problems with collisions (using vector of instances)

I wrote a for loop to check every instance of the class Wall, only the the last instance in the vector properly works

hybrid.h

 void reactTo(Player* other)
 {
     if (react)
     {
         if ((other->back<front && other->front > front) && (other->y > foot && other->y < head))
         {
             other->goAhead[0] = false;
         }
         else
         {
             other->goAhead[0] = true;

             if ((other->front >= back) && other->back < back && other->y > foot && other->y < head)
             {
                 other->goAhead[1] = false;
             }
             else
             {
                 other->goAhead[1] = true;
             }
         }
     }
     if (other->foot <= head && other->head >= head && other->x > back && other->x < front)
     {
         other->goAhead[2] = false;
     }
     else
     {
         other->goAhead[2] = true;
         if ((other->head >= foot) && other->foot < foot && foot && other->x > back && other->x < front)
         {
             other->goAhead[3] = false;
         }
         else
         {
             other->goAhead[3] = true;
         }
     }
     if (other->front > back && other->back <= front && other->head < head && other->foot > foot)
     {
         R = 0;
     }
     else
     {
         R = 1;
     }
 }

source.cpp

#include"hybrid/hybrid.h"

int main()
{
   setWindowSize(1500, 600);

   makeSequenceWall();//push back 5 Wall constructor

   Player p(300, 300,30,30,0.5,0,1,0);
   //------------
   slWindow(WINDOW_WIDTH, WINDOW_HEIGHT, "HYBRID", false);
   while (!slShouldClose())
   {
               //----------
       p.move();
       p.render();//render the player

       
       for (int i = 0; i != 5; i++)//check the collision
       {
           wallSeq.at(i).reactTo(&p);
       }

       
       for (itr = wallSeq.begin(); itr != wallSeq.end();itr++)//render the wall
       {
           itr->render();
       }
       
       slRender();
   
   }
   slClose();
   return 0;
}
