What are the top 5 national Fraternities according to size?

No it's the Kappa alpha Society. The five oldest in order are KA Society, Sigma Phi, Delta Phi, Alpha Delta Phi and Psi Upsilon. Maybe you heard Sigma Phi was the oldest national org because they are the first to have a chapter at another school.

I knew I was leaving someone out in my list of pre-Sigma Chi fraternities above, but my Saturday brain just couldn't think who it was. Thanks.

For the record:

Alpha Delta Phi Fraternity (1832): 26 active chapters and 3 affiliates (colonies) (Alpha Delta Phi Society, the co-ed society that split from the fraternity in 1992, has 4 active chapters and one affiliate.)

For the record, it should be noted that Chi Phi sometimes claims a founding date of 1824, prior to KA Society. As described by the Wiki: "The Chi Phi (ΧΦ) Fraternity is an American college social fraternity that was established as the result of three separate organizations that each were known as Chi Phi. The oldest active organization that took part in the union was originally founded in 1824 at Princeton." Per Chi Phi history, the Princeton society was founded in 1824, went dormant in 1830 and was resurrected by a nephew of one of the members in 1854. This group didn't last long, but managed to start another chapter (at Franklin and Marshall) before it died out, which in turn started a third chapter. By my count, Chi Phi currently has 59 active chapter and colonies.

I think that's it.
