You shouldn't change the template selector as they are defined on the page, you should build a more generic template and use @Input() to pass the content in and interpolate in on the page or pass in your predefined number.

<div class="row">
    <div class="col-xlg-4 col-xl-12 col-lg-12 col-md-7 col-sm-12 col-xs-12" title="FAQ" baCardClass="medium-card with-scroll">
        <FAQ [faqData]="faqData"></FAQ>
      <ul class="alShare">
        <li (click)="Show(1)">Locator</li>
        <li (click)="Show(2)">Offer</li>
        <li (click)="Show(3)">Contact</li>
        <li (click)="Show(4)">Holiday</li>
        <li (click)="Show(5)">FAQ</li>
      </ul>
    </div>
</div>

code-behind.ts

export class CodeBehind {

    public faqData: SomeObject = {//define default};

    public Show(faqToShow: number) {

        switch(faqToShow) {

        case 1: 
             this.faqData = Locator
        case 2:
        //and so on...

        }
    }
}

faq.component.ts

export class FAQ {

    @Input() public faqData: SomeObject;
}

If you do it the way above you would define the object in the parent component, however passing a number in means you could define the content within FAQ separating it from the parent, but that's up to you.

Component names are static, what you can do is pass he information to that component with something like

In your component, declare a variable

public selected: number;

In your show method, set the selected as

public show(num: number)
{
    this.selected = num;
}

and then use this selected property in your template to pass information like

<FAQ-omni selected="selected"></FAQ-omni>

In your FAQ-omni component, you can receive this variable as an input like

@Component({
    selector: 'FAQ-omni',
    templateUrl: '/template/path.html',
    inputs: ['selected']
})
export class LoginComponent
{
    public selected: number; 
}

and use this selected in your template to render/hide any information you want.

You can even use this variable to display some other component based on your condition using *ngIf directive.

<FAQ-omni *ngIf="selected == 1"></FAQ-omni>
<SomeOther-Component *ngIf="selected == 2"></SomeOther-Component>
