Yes, PAP and CHAP can be used as tunneled authentication methods with

You can only select one EAP-TTLS phase 2 method out of five options:
PAP, CHAP, MSCHAP, MSCHAPV2, and EAP since EAP-TTLS does not have a
negotiation for the used mechanism. However, EAP option (autheap) can
have multiple enabled EAP methods.
In other words, the configuration above would not result in all four
options being enabled. Instead, it would actually end up enabling just
EAP-MSCHAPv2 for phase 2. You could set phase2 parameter to "auth=PAP"
to enable PAP, to "auth=CHAP" to enable CHAP, and "autheap=MSCHAPV2 MD5"
to enable EAP with both EAP-MSCHAPv2 and EAP-MD5 allowed.
