Thank you very much for the transcription!
I think I can help you with some of the question marks:
In part 1:
Young man, young preacher, listen to me. Go at the [?] on that tree, what it means.
=> Go after Him on that tree.
Part 2:
And they walk out of the church after five minutes of counseling and they evangelist goes to [?] and the man is lost. The man is lost.
=> the evangelist goes to Denny's to eat, and the man is lost.
I remember one time we were in [?] in Peru and it was during the time of the [?] and the civil war that was going on there.
=> we were in Departamento Amazonas in Peru
=> during the time of the Sendero Luminoso
Part 3:
At what harmony Christ was [?]. Nothing.
=> And what harmony Christ with Belial? (2 Cor. 6:15) Nothing.
I was with Conrad and [?] a few months ago and I heard him preach.
=> I was with Conrad Mbewe a few months ago
A remark, in part 2 (I have not read everything so carefully, but I just came across this): Have I not right to be? Somebody must be crying out for revival. But we haven’t even got the foundations straight.
=> I would change the interpunction: Have I not right to be? Somebody must be. Crying out for revival, but we haven’t even got the foundations straight.
