Re: Which of these 5 would you recommend me to buy?
First of all, I won't recommend a model because that's your call.
So, I think the first thing you'll need is a cooling pad. That'll give you more freedom to choose something without having to worry as much for vents and heat.
If you want something that is fast in the sense that applications and the OS load quickly, you have to be looking at something with an SSD. A good processor is not that important unless you are gaming, editing, rendering, compiling or doing some other resource-intensive work. The same goes for the RAM and video card.
So, to summarize, get a decent and relatively new processor (the integrated graphics should be fine), enough RAM (8-12Gb, maybe more depending on how long you plan to keep this, don't worry about RAM speed and timings too much), and an SSD (this being the most important, although it can be expensive to get laptops that have this).
Also read reviews to see how the battery holds up against life and nature.
