Answer 1

You need to do something like:
<div *ngFor="let item of items">
// you can access your item here for example
<h1>item.id</h1>
// and you can loop again
<div *ngFor="let temp of item.custom_attributes">
<p> temp.attribute_code</p>
</div>
</div>
You can use *ngFor to iterate over an array of objects

Answer 2

In your component.js,
private myItems:any = [];
constructor(){
}
yourFunction(){
let vm = this;
items.forEach(function(val: any){
val.custom_attributes.forEach(function(myAttrs: any){
vm.myItems.push({
"code": myAttrs.attribute_code,
"description": myAttrs.value
});
});
});
}
In your html file
<div *ngFor="let myItem of myItems">
<p> Code: {{myItem.code}} </p>
<p> Description : {{myItem.description}}
</div>
