There are probably many problems inside your template and even yor models. I try to give you a possible solution: First of all, you can't make multiple POST form in your template or you have to specify the url in your template. Besides, if you want to simply search something, I suggest you to use a GET form. If you want to exclude from your search some user that have already searched, you should also add a boolean field to your user model (I don't know if your are using your own custom user model or the built in one). So, I write you what would be my approach. models.py

class Requests(models.Model):
    name = models.CharField(max_length=200)
    friend = models.CharField(max_length=200)
    answer = models.CharField(max_length=200,blank=True)
    def __str__(self):
        return self.name

class User(models.Model or inherith from AbstractUser or whatever):
    #whatever fields you have
    friend_request = models.BooleanField(default=False)

html:

    <div class='form'>
    <form action='' method='get'> <!-- Here you should use a get request if you want make a search -->
        <input type='text' class='form-control' name='name'>
        <button name='first' style='margin-top:20px;' class='btn btn-primary btn-lg'>Search</button>
    </form>
</div>
    {%if messages%}
        {%for msg in messages%}
            <div class='user' style='margin-top:50px;margin-left:310px;'>
                <form action='' method='post'>
                    {%csrf_token%}
                    <img style='width:70px;height:70px;border-radius:15px;' src='/media/{{msg.extra_tags}}'></img>
                    <p style='color:white;margin-left:5px;font-size:18px;display:inline-block;'>{{msg}}</p>
                    <input type='hidden' name='name2' value='{{msg}}'>
                    <button name='second' style='margin-left:10px;' class='btn btn-primary' onclick='myfuc()'>Send</button>
                </form>
            </div>
        {%endfor%}
    {%endif%}

Now, instead of having one view for handling many stuff, I'd split in 2 different views: 1 for handling get or post request and the other one for rendering the template. However, you can just handle in one unique view with some code like that: views.py

def friends(request):
    if request.method == 'GET':
        name = request.POST['name']
         users = User.objects.filter(username__startswith=name,friend_request=False) #this way you can filter just the users you didn't request friendship
        if not users:
            pass
        else:
            for i in users:
                messages.info(request,i.username,extra_tags=i.profile.profpic)
    if request.method == 'POST':
        name2 = request.POST['name2']
        request5 = Requests.objects.filter(name=request.user.username,friend=name2).first()
        if request5:
            pass
        else:
            requests3 = Requests(name=request.user.username,friend=name2)
            requests3.save()
return render(request,'requested.html')

I don't know exactly what you wanna achieve in the second part of the view so I left almost as it is. Let mw know if that worked for you
