Are you asking if EAP-TTLS and EAP-MSCHAPV is supported or if that's valid two factor auth?

Doing EAP-TTLS as the outer method and EAP-MSCHAPv2 as the inner meets the definition of two 
factor authentication. The certificates for TTLS are "something you have" and MSCHAPv2 relies
on credentials that are "something you know".

Hostap with an external radius server will (so far as I know/have used it) pass whatever EAP it gets to 
RADIUS, so it shouldn't (generally) care what kind of EAP methods you are using.
