Yes you do, It is £1.30 for children and £1.80 for adults
Since there is no college in Sims 3 I'll assume you're talking about Sims 2. The short answer is no. While in university a sim can't actually Try For Baby, the only way that would be possible is if you had some kind of mod. If you do have a mod installed to allow you to do this, it's probably better for you to bring this question to that creator. But to reiterate my answer: in the Sims 2, Young Adults attending University cannot Try For Baby. They can WooHoo but that will never result in a pregnancy.
The Sims 3 Generations is currently only available as an expansion pack for the PC version of the Sims 3.
Depends what town your sims are in. In the standard Sunset Valley, there are a few single women who are young enough to marry your sim if you just made them as a young adult. Some examples include Jamie Jolina and Zelda Mae, although there are others. NPCs occasionally spawn. Another alternative is that you can create one. Other towns have different female sims that are suitable as well.
You cannot. It is one of the limited features that come with playing Sims 3 on a console.
