ⲚⲎ ⲈⲦⲀⲨⲤⲰⲤ
actually it is ⲚⲎ ⲈⲦ-ⲀⲨ-ⲤⲰⲤ the word here is ⲤⲰⲤ not ⲨⲤⲰⲤ
ⲙⲉⲩⲓ means to think or consider as in (thinking of yourself)

(ϩ)ⲩⲥⲱⲥ in Acts 15:16 http://interlinearbible.org/acts/15.htm give some idea(light)?

ⲁϥⲙⲉⲩⲓ in Rom 14:6 ok!!!

here is a more accurate interlinear translation
ⲫⲏ ⲉⲧ-ϣⲟⲡ ϧⲉⲛ ⲟⲩ-ⲙⲟⲣⲫⲏ ⲛⲧⲉ ⲫⲛⲟⲩϯ
that which-exists in a-form of God (with capital G)
ⲛⲟⲩϩⲱⲗⲉⲙ ⲁⲛ ⲡ-ⲉⲧ-ⲁϥⲙⲉⲩⲓ ⲉⲣⲟϥ ⲉⲑⲣⲉ-ϥ ϣⲱⲡⲓ ⲛⲟⲩϩⲩⲥⲱⲥ ⲛⲉⲙ ⲫⲛⲟⲩϯ
a snatching not [ not a snatching ] that-he-was-thinking of [ that he thought of ] for-him becoming a ϩⲩⲥⲱⲥ with God
(ϩ)ⲩⲥⲱⲥ is a Greek word, can't be sure of its meaning probably means equivalent, if so then it will be translated "equivalent to God"
