This won't result in the same exact query, as it will result in 5 separate queries to the database, but it will give the same results.

    using (YourContext context = new YourContext())
    {
        int ACount = context.Parties.Count(_ => _.Archived == "1");
        int ICount = context.Parties.Count(_ => _.IsImportant == "1" &&  _.Archived == "0");
        int CCount = context.Parties.Count(_ => _.CreatedById == 1389 && _.Archived == "0");
        int SCount = context.Parties.Count(_ => _.CreatedById != 1389 && _.Archived == "0");
        int TotalThreadModelsCount = context.Parties.Count();
    }
