One thing that I didn’t really like (I guess it’s because I didn’t play long enough) is the number of units; I felt that you don’t have that much really different units to build;

Well, Jotunheim has a good number of choices actually. Javelin troops have great range and damage because they happen to be giants. Boulder-hurlers are a decent way to kill elite units with lots or armour like knights. Spearmen are your general purpose troops. Axeman are a good choice if you have to go up against something like a monolith that's got a very high protection value. The hirdmen and other troops don't tend to be as generally useful as spearmen, but they do have their place. Niefel giants abnd woodsmen are your elite troops that can become much more powerful with appropriate blessings.

Skratti are your water mages and blood hunters. Gygia are your sorcerors. They are both expensive, but necessary for research and other magical purposes. Niefel Jarls are your supercombatants. Give them a wraith sword, and have them cast quickness, breath of winter, blessing, attack. Then you get to watch the carnage.

Your other commanders are all fairly tough, so you can always consider building one of them every turn just to boost your forces.

Another point is magic; I was rather lost here; I was researching schools rather aimlessly...

As Nieflheim, try researching alteration till you have quickness, then construction to level 4. This gives you wraith swords, which your jarls can use to great effect.

One problem that I got late in the game is when I started being attacked; as you see in the map, I am completely surrounded by atlantis, so he kept attacking my coastal provinces (and I didn’t know how to attack underwater...),

That is Atlantis' major advantage. However, any water mage can go underwater and bring a couple of troops with him. Your Niefel Jarls are a good example.

and in the South, the C’this kept attacking also; so during the Last, I don’t know, say, 12 turns, I kept losing provinces, winning them back...without being able to do anything else; my pretender kept attacking, even some of magicians were attacking; so I found it hard to do anything else than wage war, so I never casted any rituals, or forge items, search for sites...

Niefelheim tends to have a shortage of mages thanks to how expensive they are. The most effective way to search for sites probably would have been to dedicate a single mage to each path of magic. Have them cast the site searching spells on mountain provinces first, then forests and wastelands, then plains, then farmlands. The site searching spells are located under conjuration: (water (voice of aspu) and death(dark knowledge)), evocation: (astral(arcane probing)), bloodbowl of blood), and thaumaturgy which has everything else.

Another problem was with unrest, as some of provinces that were far from my capitole (like Loria, Shade forest...) had unrest in the 80’s; and I didn’t know what to do; I tried to patrol a little, but it was very efficient; so I built a castle in a nearby province, but I am not sure it helped...

The easiest way to reduce unrest is to lower taxes. Lowering them by 5% for every 5 points of unrest will clear most unrest in about two turns. If it doesn't go down, then there's probably an unrest generating site there. Have a blood mage search there and you'll find it.
