Answer 1

Just added this on controller

  onChageType:function(component){
    var val = component.get("v.type");
    // console.log('type',val);
    if(val == 'Salesforce sObject'){
        component.set('v.isActive',false);
    }
    else{
        component.set('v.isActive',true);
        component.set("v.selectSojbect",'');
    }
},

If you are using out of box page layouts and standard edit screen, hiding/disabling a field at runtime is not possible.

However, you can set up the 'Type' picklist field as the controlling field for the 'Select SObject' picklist field. Map the values, such that if the Type is SObject then only it will render the values for SObject picklist.

This is called 'Dependent Picklists' feature.
