How about giving advice instead of giving him a hard time?
If you are going to play NLHE I would first recommend playing 1/2 instead of 2/5 - if you can.
Once you start doing that then yeah, the hand ranges you listed are a pretty good ranges to play in different positions. Whats important to remember is that when you are playing those hands you only want to raise with them, don't limp in (by limping I mean just calling the minimum to play).
When that gets tricky is when you are in late position and several people have limped in and you are now in a position where you have a medium strength hand and there is a lot of money already on the table. So you can bet, but if you do it needs to be a pretty sizeable bet (3 big blinds + 1 bb for every person who limped in). That makes it so they don't have the right
odds to call and you are more likely to get into a heads up pot. Making that raise with medium strength hands is dangerous because the hands that call you are likely to be better than what you raised with.
In general, I would advise playing that hand range, and folding very generously. Once you get a feel for the game and read some more strategy articles you will start to understand some of the nuances to the game.
2/5 is not that hard to beat live, but it is a more expensive lesson than 1/2 is (or .01/.02 online for that matter).
