It's not possible to say from one game. For one thing, we have no little idea how strong you are, since you just joined last week too and have only played 8 games.
His opening was weak. You could have busted him at move 7.
How good is my friend?

Your friend (Black) had a number of opening inaccuracies, plus the obvious blunder at the end where he overlooked a knight fork, so I'd say he's certainly under 1800, and probably under 1600:
2...g6 gives White a 52% win rate, per 365 chess. If he wants to play the French, he should play 2...d5. If he wants to play a kingside fianchetto, he maybe should have played 1...d6 to transpose into the Pirc. Those two moves ...e6 and ...g6 don't match well, I don't believe.
4...Nf6 could have been 4...d5, which strikes toward the center and forces White's bishop to lose a tempo.
5...Nd5 allows his pawns to get doubled if White plays 6. Bxd5.
6...b3 has the same drawback, which would block his queenside fianchettoed bishop. Black should be castling about now.
8...Nc6 is weak placement for that knight in that opening. That knight has no good destination square from there, and it blocks his c-pawn. Better would be 8...Nbd7, which means Black should play ...d6 first, but again, he should be castling around now.
Instead of 19...fxe5 he may have had a winning mating attack starting with 19...Qg6+, using his bishop at b7 to threaten mate at g2 after his two knights are moved out of the way, possibly as sacrifices. For him to overlook that suggests he's not in the habit of looking for Zwischenzugs. (Or is it "Zwischenzuggen"? 
)
1. e4 e6 2. d4 g6? is already an opening mistake as it weakens the dark squares around the king and basically playing passive moves to let you gain space. For example in the game you played Bg5 and forced him to play f6 which would normally mean a weak kingside, but in the game you allowed 0-0-0 which made the point irrelevant.
2. d4 d5 is the well known French defense, while other moves such as 2.. c5, b6 also makes sense to me. If black wanted to financetto so badly just start with 1. e4 g6.
After that you gained a good opening advantage with normal moves (because black was doing nothing), and after 5.. Nd5? you should have played 6. Bxd5! to take black's only active piece, double his pawns, and get to his king. The idea is 6. Bxd5! exd5 7. Bg5! which forces the very sad 7 ..f6 (else the queen is trapped) 8. exf6 Bxf6 9. Qe2+! Kf8 and this is a very easy win with black's king under fire in the center and no development.
The game should have looked like Murphy vs Duke of stupicity (I can't remember Duke of what) with an easy checkmate under 30 moves but instead you lost the game...
Note that after 7. c3?? (total waste of a move) b6??, taking the knight works the same as above on move 8. Point is if nothing else you can't just let him get away with all these weak, slow moves and let him double financetto and castle queenside and do what he want.
After 11.. 0-0-0?? this was also an easy win as you notice that your rook directly oppose the queen? 12. Bxd5! exd5?? 13. exf6! and thats a fork and also a discovery attack of Rook on the queen, winning huge material. So after 12. Bxd5 he is forced to go 12 ..g5 13. exf6 Bf6 14. Bg3 which black is at least just down a knight.
After missing that chance black is simply rolling the pawns on the kingside and you lost. The problem with your play is that you are developing simply for the sake of developing and moving pieces around. With some understanding of opening theory it is easy to notice black's opening play isn't right on many levels, and you should have been thinking of how to punish that.
Hello guys. This is a game my friend played as black, which he won. I would like to know how strong you think he is. He has only played a couple of games here so his rating is probably not accurate. I can't analyse it myself as I'm very new to chess myself.
Thanks to anyone who takes a look.
