As already noted above, you'll have no trouble at all finding recipes for all these styles on this forum alone, let alone other UK & US forums etc, along with the usual books.Beers that I generally like are:
American IPA
English IPA
APA
Amber Ale
English Bitter
The best thing you can do, the best way to learn as a new brewer, is simply to get on and brew, to experiment and learn what works for you. And if it doesn't quite work out, remember it's just a hobby and have a think why and what you'd do differently next time.
One observation - I'd argue that all the styles you've listed there are more or less the same, or at least share a common ancestry.
What sets them apart is (a) strength and (b) use of local ingredients (malt, hops & yeast).
For example you could argue American Amber is simply an English Bitter made with US malts, hops (e.g. you might see Cascade used instead of EKG), and yeast (US strains generally cleaner, English are more fruity).
So one thing you might try is to take a "standard" baseline recipe to make all these different styles.
- This could be nothing more than changing the hops & yeast
- You can also play around with when you add hops, and how much
- Or maybe changing the proportions of the grain bill (American IPA might use less crystal malt or none at all, for example)
- Or just increasing the grain bill to make it stronger (arguably either by increasing only the base malt, or just increase everything).
Experiment, have fun and report back
