Answer 1

Using readAsDataURL you can get file path and set to img tag.
jQuery(document).ready(function() {
var readURL = function(input) {
if (input.files && input.files[0]) {
var reader = new FileReader();
reader.onload = function(e) {
$('.input-img').attr('src', e.target.result);
}
reader.readAsDataURL(input.files[0]);
}
}
$("input[type='file']").on('change', function() {
readURL(this);
});
});
.custom-input-file {
position: relative;
cursor:pointer;
}
.custom-input-file .input-file-wrapper {
height: 150px;
width: 150px;
border-radius: 10px;
position: relative;
}
.custom-input-file .input-file-wrapper .input-img {
height: 100%;
-o-object-fit: cover;
object-fit: cover;
border: 1px solid #ced4da;
border-radius: 10px;
width: 100%;;
}
.custom-input-file .input-file-wrapper input[type=file] {
position: absolute;
left: 0;
width: 100%;
height: 100%;
padding: 0;
opacity: 0;
top: 0;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<div class="input-wrapper">
<div class="custom-input-file ">
<div class="input-file-wrapper ">
<img src="https://storage.googleapis.com/proudcity/mebanenc/uploads/2021/03/placeholder-image.png " class="input-img">
<input type="file" class="form-control ">
</div>
</div>
</div>

Answer 2

little bit change and add some javascrpt and jquery in it.
firslty add this
<div class="form">
<div class="grid">
<div class="form-element">
<input type="file" id="file-1" asp-for="imge1" name="imge1">
<label for="file-1" id="file-1-preview">
<div>
<span>+</span>
</div>
</label>
</div>
</div>
</div>
then add this javascript and jquery
<script>
function previewBeforeUpload(id){
document.querySelector("#"+id).addEventListener("change",function(e){
if(e.target.files.length == 0){
return;
}
let file = e.target.files[0];
let url = URL.createObjectURL(file);
document.querySelector("#"+id+"-preview div").innerText = file.name;
document.querySelector("#"+id+"-preview img").src = url;
});
}
previewBeforeUpload("file-1");
previewBeforeUpload("file-2");
previewBeforeUpload("file-3");
previewBeforeUpload("file-4");
previewBeforeUpload("file-5");
previewBeforeUpload("file-6");
previewBeforeUpload("file-7");
previewBeforeUpload("file-8");
previewBeforeUpload("file-9");
previewBeforeUpload("file-10");
</script>
Also add this CSS

}

}
.form .grid {
margin-top: 5px;
display: flex;
justify-content: space-around;
flex-wrap: wrap;
gap: 20px;
}
.form .grid .form-element {
width: 80px;
height: 80px;
box-shadow: 0px 0px 20px 5px rgba(100,100,100,0.1);
}
.form .grid .form-element input {
display: none;
}
.form .grid .form-element img {
width: 80px;
height: 80px;

}
.form .grid .form-element div {
position: relative;
