I'm sorry, I don't know where you found the translation but it doesn't hold water. "entrai", "trouvai", are 1st person singular, indicative simple past tense. "ferai" is 1st person singular, indicative future tense and it can't be any other person. "A chapel in a roof" for "Un chapelet en ferai" is just nonsense. About "chapelet": "The French word "chapelet" is a derivative of the word "chapeau" (hat), the old form of which was chapel. Originally (c. 1200), it designated a headdress, a crown of flowers and became a term for religious use by analogy with the crowns of roses, with which the heads of Marian statues were adorned (cf. rosary). Synonyms: suite, series, parade. We say a rosary of roses for a series of roses linked together longitudinally." (French Wiki, translated by Google and edited by me). "Un chapelet en ferai": "Un" = a, one, "chapelet" = rosary, crown, wreath, garland, "en" = of it, "ferai" = will make.
About "qui nous demaine": "qui" = who/that, "nous" = us (object, not subject), "demaine" = verb "demainer/démener" (link in one of my posts above) and not "demain" = tomorrow.
I forgot to translate "Une autre amie en ferai" = I'll make another lover (amie at that time didn't only mean "friend"). Btw "I will send it to you" as a translation for "À mon amie l'enverai" is wrong, it means "To my beloved (I) will send it" [To my beloved it (I) will send].
Those are just a few things.

Re. to your last link, it's an Occitan-English translator. I already said that Occitan isn't French and vice versa just like English isn't Dutch though they are Germanic languages.
