A few names (oliga onomata). This use of onoma for persons is seen in the Koiné (Deissmann, Bible Studies, p. 196f.) as in Act 1:15; Rev 11:13.
Did not defile (ouk emolunan). First aorist active indicative of molunō (1Co 8:7; 1Pe 1:4), pollution.
They shall walk (peripatēsousin). Future active of peripateō, promise of fellowship with Christ (met' emou, with me) “in white” (en leukois), as symbols of purity (Rev 7:9, Rev 7:13) like the angel (Mat 28:3), with possibly a reference to Enoch (Gen 5:22). For they are worthy (hoti axioi eisin). To walk with Christ, not worthy in the same sense as God and Christ (Rev 4:11; Rev 5:9), but in a relative sense. See Rev 16:6 for bad sense of axios.
