If the component is a component you are creating, you can add more inputs to be able to receive the desired parameters by using the @Input:
@Component({
    templateUrl: './seu-template.html',
    styleUrls: ['./seus-estilos.css'],
    selector: 'header-fix'
})
export class HeaderFixComponent{
@Input() nomeRedeSocial: string;
@Input() linhaDoTempo: string;
@Input() perfil: string;
@Input() usuario: string;
//...
And in the Appcomponent:
HTML
<header-fix 
    [usuario]="usuario" 
    [linhaDoTempo]="linhaDoTempo" 
    [perfil]="perfil" 
    [nomeRedeSocial]="nomeRedeSocial">
</header-fix>
TS
export class AppComponent {
    nomeRedeSocial: string = "Minha Rede Social";
    linhaDoTempo: string = "Linha do Tempo";
    perfil: string = "Perfil";
    usuario: string = "Usuário";
}
