What is an angel Biblically? Does it fit Felix Manalo?

Felix Manalo on the cover of the Pasugo magazine.

The Iglesia ni Cristo (or the Philippine Church of Christ) claims that Felix Manalo, the founder of their church, is an angel. First of all, what is an angel? According too the Bible, an angel is:

"[9] Of the angels he says, 'He makes his angels wind, and his servants flames on fire'. [14] Are not all angels spirits in the divine service, sent to serve for the sake of those who inherit salvation?" - Hebrews 1:9, 14 (NRSV-CE)

The verse clearly says that angels are spirits and winds, they are not people that can be touched. Felix Manalo is a man that can be touched. In short, Felix Manalo is a concrete noun. But the Bible clearly says that angels are cannot be touched, smell, or taste etch. There is no such thing as angel & man. An angel is a spirit not a man!
