All I need now is for someone knowledgeable (I mean it, I don't want somebody who has to use a dictionary to read what I just wrote to answer this) to answer me.
I am Japanese.
I'm not sure if I am eligible to answer your question, but here is my translation.
1. I lend money to my friend.
俺は友達に金を貸す。
俺 → Lend → 友達
2. My friend borrows money from me.
友達は俺に金を借りる。
友達 ← Borrow ← 俺
3. I let my friend borrow money (from me/someone else).
俺は友達に金を借りさせる／させた。
俺 → Let → 友達（友達 ← Borrow ← 俺／Someone else）
4. My friend made me lend him money.
友達は俺に金を貸させた。
友達 → Made → 俺（俺 → Lend → 友達）
5. I was made to lend money to my friend (by him/someone else).
俺は友達に金を貸させられた。
（俺 → Lend → 友達）俺 ← Was made to ← 友達／Someone else
6. My friend made me borrow him money.
友達は俺に金を借りさせた。
友達 → Made → 俺（俺 ← Borrow ← 友達）

How often do you guys convert kana to kanji when typing? Every word? Every sentence? How to Japanese people do it?
It really depends on the person.
Some people type a whole sentence and then convert it to kanji in one go, but others convert every single or several word(s).
If you are using clever Japanese input software, it converts even a long sentence fairly correctly according to the context.
Even if the sentence is not correctly converted, you can select the right 文節(segment?) using the shift key + right/left allow keys.
Using the right/left keys without the shift key let you choose a 文節 next to the one currently selected.
