401k options which is the least harmful

my company does not allow for the option of a brokeragelink account and has very limited funds to choose from that arent Vanguard target funds.

SP 500 INDEX PL CL C
SP EXT MKT IDX CL C
AF EUROPAC GROWTH R6 (RERGX)
SP TTL INTL IDX CL C
NUVEEN REAL ESTATE I (FARCX)

which of these should i choose for my 401k?
