I think all of those guys are non-tender candidates. Parra will be due for at least $1-$1.5MM in arbitration, Veras $2-$2.5MM, and Loe $2.5-$3MM. Loe has actually been pretty decent over the last couple seasons, despite that horrendous stretch last year (~3.75 ERA, 3.50 FIP). I'd probably hang onto him for next season. Veras and Parra don't seem worth it for $4.5MM total. Quite frankly, these guys just aren't terribly good at preventing the other team from parading across home plate. Non-tender them and if they're willing to sign for $.5-$1MM I'd have them back.
