Wait it's simpler then that. In template:
<div *ngIf = "name == 'a'">if a</div>
<div *ngIf = "name == 'b'">if b</div>
<div *ngIf = "name == 'c'">if c</div>
edit
If you want to make it dynamic do *ngFor let name of names and do ngIf on {{name}}
<div *ngFor="let name of names">
<p *ngIf = "name == {{name}}">Your if</p>
</div> //something like this.
