Barking at you if it just started; should fade pretty quickly if you give him absolutely no response when he does it and are mindful of only initiating any activity with him when he is relaxed and quiet.

If you have been responding with even something as simple as a "hush" command; the behavior has been reinforced and will likely get worse before it get betters as he tries harder to get your attention with the barking because it worked before. Stand strong and do not give attention.

Have you done any marker training with him? I think marker training would help a great deal in marking the point he gives up on the attention barking. Another option would be to crate him when you are busy in the house.

He's still a baby so I would not expect perfect obedience but the other barking seems like it could be handled with basic obedience training. For instance calling him to you away from the fence and having him heel with attention when walking by other dogs etc.

That being the goal realize at 7 months you start in the least distractive environment and build on successes so it might be awhile before you can call him away from the fence with the distraction of another dog but keep a long line on him so that you can reel him in with praise and a FABULOUS reward when he gets to you.
