All of the Fathers used the Deuterocanon. Only St. Jerome and maybe a few others disagreed. I think Jerome is the only one though.
St. Gregory the Theologian, St. John of Damascus and many Church Fathers did not include the deuterocanonicals in their Bible canon. Many Church Fathers. Some others quoted them, sometimes as Scripture, even when they didn't consider them canonical, including St. Athanasius (he excluded them from his canon). See my links above for some references.
Even St Jerome considered them inspired scriptures, and all his changing views on them came from his hebrew love. But in the early Church, not part of the canon does not equal "not inspired" and Church Fathers considered them inspired. I will quote the Fathers you mentioned.
St John of Damascus wrote:
And hence it is that in the Old Testament
the use of images was not common. But after God (Jn 1:14, Tit. 3:4) in His bowels of pity became in truth man for our salvation, not as He was seen by Abraham in the semblance of a man, nor as He was seen by the prophets, but in being truly man, and "after He lived upon the earth and dwelt among men, (Bar. 3:37)
An Exposition of the Orthodox Faith, Book IV, Chapter XVI.
He considers Baruch and Old Testament book.
Some, again, have a prophetic sense, and of these some are in the future tense: for instance, He shall come openly, (Psalm 50:3) and this from Zechariah, Behold, thy King cometh unto thee, (Zech. 9:9) and this from Micah, (Mic. 1:3) Behold, the Lord cometh out of His place and will came down and tread upon the high places of the earth. But others, though future, are put in the past tense, as, for instance, This is our God: "Therefore He was seen upon the earth and dwell among men," (Baruch 3:37)
and The Lord created me in the beginning of His ways for His works (Prov. 8:22), and Wherefore God, thy God, anointed thee with the oil of gladness above thy fellows, and such like. (Psalm 14:7) St. John of Damascus, An Exposition of the Orthodox Faith, Book IV, Chapter XVII
He places Baruch on same level as Zechariah or Micah.The divine Scripture likewise saith that 'the souls of the just are in God's hand’ [Wisdom 3:1]
and death cannot lay hold of them." John Damascene, Orthodox Faith, 4:15
And he does the same with maccabees etc.
For St St. Athanasius is the same thing.
"[T]he sacred writers to whom the Son has revealed Him
, have given us a certain image from things visible, saying, 'Who is the brightness of His glory, and the Expression of His Person;' [Heb 1:3] and again, 'For with Thee is the well of life, and in Thy light shall we see lights;' [Ps 36:9] and when the Word chides Israel, He says, 'Thou hast forsaken the Fountain of wisdom;' [Baruch 3:12]
and this Fountain it is which says, 'They have forsaken Me the Fountain of living waters' [Jer 2:13]"  Athanasius the Great: Defense of the Nicene Faith
"And where the sacred writers say
, Who exists before the ages,' and 'By whom He made the ages,’ [Heb 1:2] they thereby as clearly preach the eternal and everlasting being of the Son, even while they are designating God Himself. Thus, if Isaiah says, 'The Everlasting God, the Creator of the ends of the earth;’ [Is 40:28] and Susanna said, 'O Everlasting God;' [Daniel 13:42-Susanna] and Baruch wrote, 'I will cry unto the Everlasting in my days,' and shortly after, 'My hope is in the Everlasting, that He will save you, and joy is come unto me from the Holy One;' [Baruch 4:20,22]
" Athanasius the Great: Discourses Against the Arians
Since, however, after all his severe sufferings, after his retirement into Gaul, after his sojourn in a foreign and far distant country in the place of his own, after his narrow escape from death through their calumnies, but thanks to the clemency of the Emperor,- -distress which would have satisfied even the most cruel enemy,-- they are still insensible to shame, are again acting insolently against the Church and Athanasius; and from indignation at his deliverance venture on still more atrocious schemes against him, and are ready with an accusation, fearless of the words in holy Scripture, 'A false witness shall not be unpunished;’ [Proverbs 19:5] and, 'The mouth that belieth slayeth the soul;' (Wisdom 1:11)
we therefore are unable longer to hold our peace, being amazed at their wickedness and at the insatiable love of contention displayed in their intrigues. [Athanasius the Great: Defence Against the Arians
etc etc etc
St Jerome also.Does not the SCRIPTURE say: 'Burden not thyself above thy power' [SIRACH 13:2]
Jerome, To Eustochium, Epistle 108
still our merriment must not forget the limit set by Scripture
, and we must not stray too far from the boundary of our wrestling-ground. Your presents, indeed, remind me of the sacred volume, for in it Ezekiel decks Jerusalem with bracelets, (Eze. 16:11) Baruch receives letters from Jeremiah,(Jer. 36, Bar. 6)
and the Holy Spirit descends in the form of a dove at the baptism of Christ.(Mt. 3:16) Jerome, To Eustochium, Epistle 31:2
A. DO YOU EXPECT ME TO EXPLAIN THE PURPOSES AND PLANS OF GOD? THE BOOK OF WISDOM
GIVES AN ANSWER TO YOUR FOOLISH QUESTION: [Sir 3:21] "LOOK NOT INTO THINGS ABOVE THEE, AND SEARCH NOT THINGS TOO MIGHTY FOR THEE." AND ELSEWHERE, "Make not thyself overwise, and argue not more than is fitting." And in the same place, "In wisdom and simplicity of heart seek God." You will perhaps deny the authority of this book
;" "Jerome, "Against the Pelagians
Etc etc etc
The issue of the Fathers and deuterocanonicals has been dealt with as far as protestants are concerned.
