Thank you for taking the time to play the game!
And now about your questions:
1. Each enemy card has as much HP and deals as much damage as the card's value. One token increases the card's value by one, therefore, it will have +X more HP and will deal +X more damage.
2. If you don't do anything with an enemy card (nor dodged nor damaged), this would mean that the enemy hits you. It deals as much damage to you as much the card is worth. After that, enemy cards go to the discard pile at the end of the round except for bosses and the Ace of Spades.
3. The latter, you fill them up. (If there are other enemies already on the table, you only have to draw up to as many cards as the tier indicates (e.g. if you've got one enemy card in play and you're in tier 2, you only have to draw 3 more cards so you'll have 4 enemy cards on the table in total).)
4. All d10-s are getting rerolled, yes. For ability cards, you should think about your "hand" as slots. You have one slot for each suit. You can keep you cards in your hand, but if you draw from, let's say, a spade and your spade slot is already occupied, you have to discard the spade card first to be able to draw a new one.

I hope these answered your questions. And also, big thank you for playing the game dispite the manual being in a draft state!
